Dibromido(2,3-di-2-pyridyl­pyrazine-κ(2) N (2),N (3))platinum(II)

The Pt(II) ion in the title complex, [PtBr(2)(C(14)H(10)N(4))], has a slightly distorted square-planar environment defined by the two pyridyl N atoms of the chelating 2,3-di-2-pyridyl­pyrazine ligand and two bromide anions. In the crystal, the pyridyl rings are considerably inclined to the least-squares plane of the PtBr(2)N(2) unit [maximum deviation = 0.064 (2) Å] with dihedral angles of 65.2 (2) and 66.0 (2)°. The nearly planar pyrazine ring [maximum deviation = 0.020 (5) Å] is almost perpendicular to the unit plane with a dihedral angle of 89.2 (2)°. Two independent weak inter­molecular C—H⋯Br hydrogen bonds, both involving the same Br atom as a hydrogen-bond acceptor, give rise to chains running along the a and b axes, forming a layer structure extending parallel to (001). The complexes are stacked in columns along the a axis. When viewed down the b axis, the successive complexes stack in the opposite direction.
