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.

The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2
