- Abstract
- The synthesis of novel group 9 metal complexes containing the S,S′-chelate ligands, Li2S2C2B 10H10 (2a) and LiS(S=PMe2)C2B 10H10 (2b), is described. Two new dinuclear complexes of the type [{(cod)M}2(S,S′-S2C2B 10H10)] (cod = 1,5-cyclooctadiene; M = Rh (3a), or Ir (3b)) were synthesized by the reaction of chloride-bridged dimers [M(μ-Cl)(cod)]2 with one molar equivalent of the corresponding dilithium dithiolato ligand Li2S2C2B 10H10 (2a). X-ray crystal structure analysis of 3a revealed a dinuclear structure in which each (cod)Rh unit is attached to a distinct sulfur atom of a 1,2-dithio-o-carboranyl ligand (2a). Additionally, the electrochemical properties of 3a and 3b were investigated by cyclic voltammetry. In an analogous manner, reaction of the lithium dithiolato ligand LiS(S=PMe2)C2B10H10 (2b) with Cp*CoI2(CO) produced a mononuclear dithiolato complex, [Cp*CoI{(S,S′-S(S=PMe2)C2B10H 10)}] (4), which was characterized by single-crystal X-ray analysis.
