Tetra-chlorido(1,10-phenanthroline-κN,N')platinum(IV) acetonitrile hemisolvate.

The asymmetric unit of the title compound, [PtCl(4)(C(12)H(8)N(2))]·0.5CH(3)CN, contains two crystallographically independent Pt(IV) complexes with very similar geometry and one solvent mol-ecule. In the complexes, each Pt(IV) ion is six-coordinated in a distorted octa-hedral environment by two N atoms of the 1,10-phenanthroline ligand and four Cl atoms. Because of the different trans effects of the N and Cl atoms, the Pt-Cl bonds trans to the N atom are slightly shorter than those trans to the Cl atom. The compound displays numerous inter-molecular π-π inter-actions between six-membered rings, with a shortest centroid-to-centroid distance of 3.654 Å. There are also weak intra- and inter-molecular C-H⋯Cl hydrogen bonds.
