摘要：

The 31P n.m.r. spectra of the cis and trans isomers of (Pt2(μ-Cl)2(COEt)2 (PMe2Ph)2] reveal 1J(PtP) coupling constants of ca 5400 Hz. The crystal structure of the trans isomer has been determined by X-ray diffraction methods. The PtP and PtC bond lengths are 2.209(1) and 1.972(5) Å. The μ-PtCl distances, 2.498(1) Å trans to COEt and 2.393(1) Å trans to PMe2Ph, suggest that, relative to phosphine, σ-carbon donor ligands exert a greater trans-influence in binuclear complexes than they do in mononuclear platinum(II) derivatives. © 1979.
