Abstract

The two phosphine ligands, dppm and PPh3, readily react with [Pt(9S3)Cl2] to form heteroleptic thioether−phosphine complexes with elongated square pyramidal structures [S2P2 + S1] in the solid state. Their solution NMR data are also similar, and both exhibit fluxional 9S3 ligands. The enhanced basicity and chelate ring strain of the dppm ligand over PPh3 are observed structurally, electrochemically, and spectroscopically, resulting in characteristic chemical shift changes in the 31P and 195Pt NMR spectra of the two complexes.
