The crystal structure of ((cyclohexylamino){(Z)-2-[(E)-5-methoxy-3-nitro-2-oxidobenzylidene-κO]hydrazin-1-ylidene-κN ²}methanethiolato-κS)(dimethyl sulfoxide-κS)platinum(II): a supramolecular two-dimensional network

Abstract

The PtII atom in the title complex, [Pt(C15H18N4O4S)(C2H6OS)], exists within a square-planar NS2O donor set provided by the N, S, O atoms of the di-anionic tridentate thiosemicarbazo ligand and a dimethyl sulfoxide S atom. The two chelate rings are coplanar, subtending a dihedral angle of 1.51 (7)°. The maximum deviation from an ideal square-planar geometry is seen in the five-membered chelate ring with an S—Pt—S bite angle of 96.45 (2)°. In the crystal, molecules are linked via N—H...O, C—H...O, C—H...N and C—H...π interactions into two-dimensional networks lying parallel to the ab plane. The conformations of related cyclohexylhydrazine-1-carbothioamide ligands are compared to that of the title compound.
