The borderline between the cis and trans configurations in square-planar diarylplatinum(II) complexes with triethylphosphane ligands [Pt(Ar) 2(PEt3)2] [Ar = 2,4,6-trimethylphenyl (mesityl), 2,6-dimethylphenyl, 2-methylphenyl, 3-methylphenyl, 4-methylphenyl and phenyl] has been investigated by a combination of multinuclear ( 1H, 13C, 31P and 195Pt) NMR spectroscopy, X-ray crystallography and quantum chemical (DFT) calculations. When formed under thermodynamic conditions, the complexes show a clear cut-off between cis (tolyl and phenyl complexes) and trans (2,6-xylyl and mesityl complexes). The syn and anti stereoisomers were identified for the 2-methylphenyl and 3-methylphenyl derivatives. Calculated data (structural isomers or NMR) are in excellent agreement with experimental findings. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
