摘要：

The four complexes [MCl(C5Me5)(N <^> S)](PF6), M = Rh, Ir; N <^> S = 1-methyl-2-(methylthiomethyl)-1H-benzimidazole (mmb) and 1-methyl-2-(tert-butylthiomethyl)-1H-benzimidazole (mtb) were synthesized and characterized by spectroscopy, electrochemistry and X-ray crystallography (as methanol solvates). The essential coordination features, viz., longer M-S (ca. 2.38 Angstrom) and shorter M-N bonds (ca. 2.09 Angstrom) in five-membered chelate rings are common to all four species. Cyclic voltammetry reveals irreversible two-electron reduction to M-I complexes and partially reversible oxidation to Ir-IV species for [IrCl(C5Me5)(mtb)](+). The results are discussed in comparison with those obtained for alpha-diimine (N <^> N) complexes of the [MCl(C5Me5)](+) fragments. (C) 2000 Elsevier Science S.A. All rights reserved.
