Bis(1,10-phenanthrolin-1-ium) hexa­bromidoplatinate(IV) dihydrate

The asymmetric unit of the title compound, (C(12)H(9)N(2))(2)[PtBr(6)]·2H(2)O, contains a protonated 1,10-phenanthroline cation (H-phen), one half of a [PtBr(6)](2−) anionic complex and a solvent water mol­ecule. The Pt(IV) ion is located on an inversion centre and is coordinated in an octa­hedral environment by six Br atoms. The crystal structure displays numerous inter­molecular π–π inter­actions between six-membered rings of H-phen, with a shortest centroid–centroid distance of 3.670 (5) Å, and inter­molecular N—H⋯O, O—H⋯Br and O—H⋯N hydrogen bonds.
