Abstract

Ligands incorporating two sulphur atoms directly connected to the carbon atoms of the unit 7,8-dicarba-nido-undecaborate (1-) have been shown to coordinate via the sulfur groups, and for RuII or RhIII additional participation of the unit B(3)-H in the coordination is observed. Mercury (II) is an exception, and HgC2B3 (metal-to-open-face bonding) has been demonstrated regardless of the presence of the two sulfur atoms. This coordination has been proved unambiguously by the crystal structure of [Hg(Ls2c5)(PPh3)] where Ls2c52- = {7,8-μ-(SCH2S)-7,8-C2B9H92-}. © 1994.
