The crystal structure of five tetracoordinate bis-cationic platinum(II), complexes containing the chelating ligand 2,6-bis (methylthiomethyl) pyridine (SNS) and para-substituted pyridines [Pt(SNS)p-X-py](2+) (p-X = CN, COOH, NH2, Cl, CH3) have been determined by X-ray diffraction. In all complexes SNS behaves as a tridentate neutral ligand, with the two sulfur atoms in trans positions to each other and an approximate C-2 symmetry with the two methyl groups on the opposite sides of the coordination plane. The fourth position, trans to the nitrogen atom-of SNS, is occupied by a para-substituted pyridine systematically rotated with respect to the platinum coordination plane. No Pt-Pt and ligand pi-pi interactions are present.

Abstract

The crystal structure of five tetracoordinate bis-cationic platinum(II), complexes containing the chelating ligand 2,6-bis (methylthiomethyl) pyridine (SNS) and para-substituted pyridines [Pt(SNS)p-X-py](2+) (p-X = CN, COOH, NH2, Cl, CH3) have been determined by X-ray diffraction. In all complexes SNS behaves as a tridentate neutral ligand, with the two sulfur atoms in trans positions to each other and an approximate C-2 symmetry with the two methyl groups on the opposite sides of the coordination plane. The fourth position, trans to the nitrogen atom-of SNS, is occupied by a para-substituted pyridine systematically rotated with respect to the platinum coordination plane. No Pt-Pt and ligand pi-pi interactions are present.
