Tetra­chlorido(1,10-phenanthroline-κ(2) N,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 mol­ecule. In the complexes, each Pt(IV) ion is six-coordinated in a distorted octa­hedral 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 inter­molecular π–π inter­actions between six-membered rings, with a shortest centroid-to-centroid distance of 3.654 Å. There are also weak intra- and inter­molecular C—H⋯Cl hydrogen bonds.
