Abstract

Reconsideration of the "rule-breaking" rhodathiaborane 8,8-(Ph₃P)₂-8,7-nido-RhSB₉H₁₀, its 9-OEt and dppe analogues, reveals the existence of agostic CH ? Rh (from PPh₃) bonding which accounts for its molecular structure. Deprotonation [H(9, 10) bridging proton] "switches off" this agostic bonding and affords a closo cluster. This structural change is fully reversible on reprotonation.
