The crystal structure of ((cyclo-hexyl-amino){(Z)-2-[(E)-5-meth-oxy-3-nitro-2-oxido-benzyl-idene-κ O]hydrazin-1-yl-idene-κ N 2}methane-thiol-ato-κ S)(dimethyl sulfoxide-κ S)platinum(II): a supra-molecular two-dimensional network

Abstract

The Pt^II 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 thio-semicarbazo 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, mol-ecules are linked via N-H⋯O, C-H⋯O, C-H⋯N and C-H⋯π inter-actions into two-dimensional networks lying parallel to the ab plane. The conformations of related cyclo-hexyl-hydrazine-1-carbo-thio-amide ligands are compared to that of the title compound.
