Cp * Ir(PMe 3 )Cl 2 ( 1 ) reacts with chalcogenide ligand sources such as (NH 4 )S x (x ≈ 10), (NEt 4 ) 2 Se 6 , and H 2 Se to yield the half‐sandwich complexes Cp * Ir(PMe 3 )(S n ) [ n = 4 ( 2a ), 6 ( 4a )] and Cp * Ir(PMe 3 )(Se n ) [n = 2 ( 5b ), 4 ( 2b )]. Desulfurization of 4a by PPh3 leads to Cp * Ir(PMe 3 )(S 5 ) ( 3a ), while both 4a and 3a react with excess P( n Bu) 3 to give 2a . The geometries of the cyclo ‐oligochalcogenide ligands in 4a and 2b have been determined by X‐ray crystallography.
