摘要：

Cp*Ir(PMe3)Cl2 (1) reacts with chalcogenide ligand sources such as (NH4)2S(x) (x almost-equal-to 10), (NEt4)2Se6, and H2Se to yield the half-sandwich complexes Cp*Ir(PMe3)(S(n)) [n = 4 (2a), 6 (4a)] and Cp*Ir(PMe3)(Se(n)) [n = 2 (5b)]. Desulfurization of 4a by PPh3 leads to Cp*Ir(PMe3)(S5) (3a), while both 4a and 3a react with excess P(nBu)3 to give 2a. The geometries of the cyclo-oligochalcogenide ligands in 4a and 2b have been determined by X-ray crystallography.
