Abstract: The PtIV ion in the title complex, [PtBr4(C10H9N3)], is six-coordinated in a slightly distorted octahedral environment by two pyridine N atoms from a chelating di-2-pyridylamine (dpa) ligand and four Br- anions. The complex molecule has mirror symmetry, with the PtIV 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 molecules are connected by intermolecular N-H...Br hydrogen bonds, forming chains along [001]. Intermolecular C-H...Br hydrogen bonds and [pi]-[pi] interactions between the pyridine rings [centroid-centroid distance = 3.667 (4) Å] are also observed.
