Additions and Corrections 1997, Volume 36 Antje Schrodt, Anton Neubrand, and Rudi van Eldik*: Fixation of Co2 by Zinc(II) Chelates in Alcoholic Medium. X-ray Structures of {[Zn(cyclen)]3(µ3-Co3)}(ClO4)4 and [Zn(cyclen)EtOH](ClO4]2. Pages 4579 and 4581: The crystal structure data for the µ3carbonate complex quoted in the Abstract and in Table 1 (for complex 1) are in error. They should read as follows: “Crystal data: orthorhombic; space group Pbca; a ) 21.852(5) Å, b ) 21.854(5) Å, c ) 21.845(5) Å;...” During the structure analysis we first considered the possibility of a cubic structure and tried to find the 3-fold axis for all space diagonals. However, only one was found, and the other diagonals clearly showed differences in the observed intensities. Further refinement showed that the space group Pbca fits much better to all the observed reflections. IC980050T S0020-1669(98)00050-0 Published on Web 09/12/1998
