Abstract

Reaction of Cs[6-arachno-SB₉H₁₂] with [RhCl(CO)(PPh₃)₂] yields the known complex [8-CO-8,8-(Ph₃P)₂-8,7-nido-RhSB₉H ₁₀], 1. In contrast, treatment of the same thiaborane with [RhCl(CO)(PPh₃)]₂ affords a number of 12-vertex dirhodathiaboranes of the type [2,3-(CO)₂-µ_2,3-CO-2,3-(PPh₃) ₂-7-X-2,3,1-closo-Rh₂SB₉H₈] in modest yields. For X = H, 3a, and X = Cl, 4, single crystal X-ray diffraction studies are reported; crystals of 3a contain the compound with X = OH, 3b, in approximately 28% occupancy. © 1997 Elsevier Science Ltd.
