Racemic (RS(C),SR(S))-(2-{[1-allyl-oxy-carbonyl-3-(methyl-sulfanyl)prop-yl]iminometh-yl}phenyl-κS,N,C)chlorido-platinum(II).

The title compound, [Pt(C(15)H(18)NO(2)S)Cl], was obtained by the cyclo-metallation reaction of cis-bis-(benzonitrile)dichlorido-platinum(II) with N-benzyl-idene-l-methio-nine allyl ester in refluxing toluene. The Pt(II) atom has a square-planar geometry and is tetra-coordinated by the Cl atom and the C, N and S atoms from the benzyl-idene methio-nine ester ligand. In the crystal structure, the S atoms show opposite chiral configurations with respect to the α-carbon of the methio-nine, reducing steric repulsion between the methyl and allyl ester groups.
