Racemic (RSC,SRS)-(2-{[1-allyloxycarbonyl-3-(methylsulfanyl)propyl]iminomethyl}phenyl-κ3S,N,C1)chloridoplatinum(II)

Abstract

The title compound, [Pt(C15H18NO2S)Cl], was obtained by the cyclometallation reaction of cis-bis(benzonitrile)dichloridoplatinum(II) with N-benzylidene-l-methionine allyl ester in refluxing toluene. The PtII atom has a square-planar geometry and is tetra-coordinated by the Cl atom and the C, N and S atoms from the benzylidene methionine ester ligand. In the crystal structure, the S atoms show opposite chiral configurations with respect to the α-carbon of the methionine, reducing steric repulsion between the methyl and allyl ester groups.
