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 π–π inter­actions between the pyridine rings [centroid–centroid distance = 3.667 (4) Å] are also observed.
