Au(nBuPPh2){(Ph2PS)3C}].CH3CN: an irregular three-coordinate AuI complex

Abstract

The molecule of [n-butyl(diphenyl)phosphine-P][tris(diphenylthiophosphinoyl)methanido-S,S']gold(I) consists of an n-butyldiphenylphosphine ligand coordinated to the Au I center with a normal Au-P distance [2.275 (4) A], and a tris(diphenylthiophosphinoyl)methanide ligand coordinated to the Au I center through two of the S atoms with two strikingly different Au-S distances [2.326 (4) and 2.894 (4) A]. The Au I center has T-shaped coordination geometry
