Bis(di-2-pyridyl­amine-κ(2) N (2),N (2’))platinum(II) dibromide monohydrate

The asymmetric unit of the title compound, [Pt(C(10)H(9)N(3))(2)]Br(2)·H(2)O, contains two crystallographically independent half-mol­ecules of the cationic Pt(II) complex, two Br(−) anions and a lattice water mol­ecule; an inversion centre is located at the centroid of each complex. Each Pt(II) ion is four-coordinated in an essentially square-planar environment by four pyridine N atoms derived from the two chelating di-2-pyridyl­amine (dpa) ligands, and the PtN(4) unit is exactly planar. The chelate ring formed by the dpa ligand displays a boat conformation, with dihedral angles between the pyridine rings of 35.9 (2) and 41.0 (2)°. The complex cations, Br(−) anions and solvent water mol­ecules are linked by O—H⋯Br, N—H⋯Br, C—H⋯O and C—H⋯Br hydrogen bonds, forming a three-dimensional network.
