title: Tetra-bromido(di-2-pyridyl-amine-κ(2)N(2),N(2'))platinum(IV).
abstract: The Pt(IV) ion in the title complex, [PtBr(4)(C(10)H(9)N(3))], is six-coordinated in a slightly distorted octa-hedral environment by two pyridine N atoms from a chelating di-2-pyridyl-amine (dpa) ligand and four Br(-) anions. The complex mol-ecule has mirror symmetry, with the Pt(IV) atom, two Br atoms and the central N atom of the dpa ligand lying on the mirror plane. The dpa ligand is not planar, showing a dihedral angle of 34.7 (2)° between the pyridine rings. The complex mol-ecules are connected by inter-molecular N-H⋯Br hydrogen bonds, forming chains along [001]. Inter-molecular C-H⋯Br hydrogen bonds and π-π inter-actions between the pyridine rings [centroid-centroid distance = 3.667 (4) Å] are also observed.
