Diplatinum(0) complexes [Pt2(µ-R2PCH2PR2)3(PPh3)n], n= 0–2: the molecular structure of the complex with R = Me, n= 1

Abstract

Two new structural type of binuclear platinum(0) complexes of formula [Pt₂(µ-R₂PCH₂PR₂)₃(PPh₃)], (2), and [Pt₂(µ-R₂PCH₂PR₂)₃(PPh₃)₂], (3), have been characterized by n.m.r. spectroscopy and, for (2; R = Me), by X-ray crystallography; steric requirements of R determine the preferred structure and complexes (2; R = Me or Et) are shown to contain both 3-co-ordinate and 4-co-ordinate platinum(0) centres.
