cis-Dichloro(dimethyl sulfoxide-S)(2-methoxypyridine-N)platinum(II)

The title complex, [PtCl₂(C₆H₇NO)(C₂H₆OS)], exhibits square-planar geometry. The plane of the pyridine ring makes a dihedral angle of 67.2 (3)° with the square plane of the metal center. The S-O bond is nearly aligned with the adjacent Pt-N bond, leaving the methyl groups of the di­methyl sulfoxide ligand to stagger the Pt-Cl bond.
