Preparation of Bis(tetrabuty1ammonium) Octa(p3-chloro)hexakis(trifluoromethanesu1fonato)-octahedra -hexamolybdate(2-), (BU~N)~[MO~CI~~(CF~SO~)~~]: A Versatile Starting Material for Substituted Mo(I1) Clusters Containing the [Mo6Cli814+ Core Dean H. Johnston, Dennis C. Gaswick, Mark C. Lonergan, Charlotte L. Stern, and D u w a r d F. Shriver* Received November 8, 1991 The useful starting material (Bu~N)~[Mo~C~~~(CF~SO~)~~], was synthesized in high yield by the reaction of ( B U ~ N ) ~ [ M O ~ C I ~ ~ C ~ ~ ~ ] with AgCF3S03in CH2C12.The crystal structure of the benzyltrimethylammonium salt of this cluster reveals an average Mo-Mo distance of 2.593 (4) A, an average M o 4 distance of 2.465 (4) A, and an average Mc-0 distance of 2.126 (9) A.
