When possible the thermodynamic information is given in consistent units a t 25% Results from both spectroscopic and nonspectroscopic methods are included in the table. Relatively little is directly indexed on hydrogen bonding in solids, although the hook does seem to cover that field better than the index would indicate. Those interested in hydrogen bonding in solids will want t o consult Hamilton and Ibers ["Hydrogen Bonding in Solids," Benjamin, 19681 and the recent review of Novak ["Structure and Bonding," Vol. 18, Springer-Verlag, 19741. The somewhat specialized recent book of Green ["Hydrogen Bonding by C-H Groups," Halsted Press, 19741will be of interest t o some. Reviewer complaints of book prices have had no more effect on the price of books than complaints about the weather have changed the weather. However, a t aver seven cents a page this is an expensive book which is out of the reach of purchase by most graduate students who would find it useful. In spite of this, anyone working directly in the field of hydrogen bonding cannot afford to be without access to this book. H. Lawrence Clever Emory University Atknta. Georgia 30322

In a preceding review (this Journal, 52, 000, 19751, I discussed the first three volumes of the "Benchmark Papers in Inorganic Chemistry," an intensive look a t an area of inorganic chemistry. In the present review, also dealing with "Benchmark Papers," I will attempt to provide some perspective on the hooks in this program that are peripheral t o the main body of chemistry, such as the present volume in the "Geology" series. Apparently the publisher sent m e this volume because germanium geochemistry should he "inorganic chemistry.'' Let me set the record straight a t the outset: My only previous contact with geochemistry has been limited to the folklore that one of the world's richest deposits of germaniumbearing lignite was beneath Byrd Stadium in College Park. So, naturally, the first thing I did was look up "lignite," "coal," and "brown coal" in the index. No mention of College Park! I include this chauvinistic aside merely t o he able to point out that I . had not read four pages of introduction before I came across references to germanium in lignite, brown coal, and coal which were not in the index either. In contrast t o the volumes reviewed previously, I found the indexes disappointing. If I sought t o find out what J. T. Wassan, for example, had done in this area, the author index directed
me neither to his reprinted articles nor to the subject matter where he was cited, hut to the References section a t the end of the appropriate paper, leaving me to fumble through that paper hoping to catch all significant references. Simply scanning the reference lists would have done as much and saved seven pages of print (at 561 page). Also, in contrast t o the favorable impression I received from the first three volumes, that many references were included where complete papers could not be, Weber a t one point stated, ". . . only four of his many fine papers . are included . . ." Did not a t least a few of these fine papers deserve references? A "Benchmark" volume cannot hope to be a closed system. Despite my initial handicaps, I felt that the papers and their explanations were clear. Feeling that some of my negative feelings about portions of this book might really be a reflection of my parochialism as an inorganic chemist, I asked a geochemist friend to give me a few opinions. They were, in part: "Neither . . . editor offer(s) any justification for a whole volume dedicated t o just one element. The book would be fine for a graduate level course on the geochemistry of germanium but I have never heard of such a specialized course." He also pointed out what I had noticed: The supposed aim of providing hard-to-get articles or those not previously available in English was not met. The entire "Benchmark" program is an ambitious one. There are 17 series ranging from "Animal Behavior" to "Nuclear Physics," of which 50 volumes had appeared by
..
.. .
the several biological series. Titles in the latter include "Hormones and Sexual Behavior," in the "Animal Behavior" series, "Anhydrohiosis" ("Biological Concepts"), "Contraeeption" ("Human Physiology"), and "Microbial Metabolism" PMicrohiology"). The extent to which these series will prove useful to the educator and research chemist will depend largely on the expertise and judgment of the editors involved. James E.

If you are considering a research program in the area of the organometallic chemistry of titanium, zirconium, and hafnium, this book is the place to start. The authors present, in a well organized and highly condensed style, the results of almost 900 publications which cover the period from the inception of work in this area to December 1973. The properties of a large number of campounds are presented in tabular form and structural formulas are displayed for the significant compounds. The 261 pages of text are divided into eight chapters. After a brief introduction t o establish a perspective for the chemical and physical properties of the cyclopentadienyl derivatives, chapters follow on: the alkyl and aryltitanium (IV) compounds; *-bonded derivatives of titanium(lV); arganometallic compounds of zirconium(1V) and hafnium(1V); complexes of titanium and aluminum (including related systems); organometallic compounds of titanium(II1) and zirconium(III), organometallic com~ o u n d sof titanium(II), zirconium(I1) and hafnium(l1); and finally the reactions of dinitrogen with titanium (and zirconium) compounds. I t may not be a book to go t o bed with, but i t should be available to every serious research worker in this field. Edwin M. LarJen Uniwrsny of Wisronsin-Madison Madison. 53706

The user of this reference hook who plunges into the table of eleetrochemieal data after a glance a t the list of abbreviations will immediately learn two things: (1) T h e volume is rich in information which is relatively easy to decode and (2) One should read the preface first.
Within the restrictions, which are clearly stated in the preface, the authors have produced a most useful work. The most hothersome limitation in the reviewer's opinion is that of the number of carbon atoms (only compounds with 11 and fewer carbons are included) and this prohlem will be largely alleviated by the publication in 1975 of Volume B of Part 1of the series. The heart of the book is Table I-Electrochemical Data-which contains essential polarographic (in the hroader sense) information on 2015 compounds and covers 480 of the volume's 727 pages. Nine other tables are included which are either supplements or indexes t o Table I. Any attempt to adequately describe the information that is contained in the 28 columns of Table I would unduly lengthen this review. A particularly useful feature is a column headed CIM (course and mechanism). An entry for a compound in this column refers to Table 111 which gives equations for half reactions and coupled chemical processes along with rate and equilibrium constants where available. About onethird of the compounds have an entry in this column. Entry to Table I for most users will be through Table IV, an alphabetical listing of com~oundsfollowed hv code numbers. Frequent use is made of common names. A second index groups compaunds by classes. Organometallics (many ferrocenes made the 11carbon cut) are listed by metal. Table VII which is an index by technique allows one to locate (or just count) studies reporting use of any of the some 50 teehniques included in the survey. Similar indexes are by solvent and by indicating electrode. Finally a key t o literature cited grouped by journal and an author index are included. A minor criticism is the extremely small size of the print employed in the keys to use of the tables. Larger print is, fortunately, used in the tables. In the course of using the book two errors in the author index were noted and one class of compaunds was found listed in the index for which there were no entries. One case of mis-numbering was found in the C/M column although the correct mechanism was on the same page of Table 111 and easily found. The authors have done a masterful iob of rnnkin hook numbers for -~the ~ - usable. ~ - Code . the compounds are placed in both the first and last columns of Table I t o facilitate following the lines. Abbreviations are chosen so as to make sense and to maximize the information conveyed. Lists of abbreviations are provided inside the front and hack covers and on a separate unbound page. This book will prove useful to anyone interested in obtaining a clear and concise picture of the electrochemistry of a compound or a group of compounds. In many, if not most, cases sufficient hard information is available to obviate the necessity of seeking the original literature reference. This ~- is after all the difference between a useful reference vulume and a l ~ s tof e m pounds with hterature references. ~
