Abstract:
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 mol-ecule. The Pt(IV) ion is located on an inversion centre and is coordinated in an octa-hedral environment by six Br atoms. The crystal structure displays numerous inter-molecular π-π inter-actions between six-membered rings of H-phen, with a shortest centroid-centroid distance of 3.670 (5) Å, and inter-molecular N-H⋯O, O-H⋯Br and O-H⋯N hydrogen bonds.

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
