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

The Pd(II) ion in the title complex, [PdBr(2)(C(14)H(10)N(4))], is four-coordinated in a slightly distorted square-planar environment by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl­pyrazine (dpp) ligand and two bromide anions. The pyridine rings are considerably inclined to the least-squares plane of the PdBr(2)N(2) unit [maximum deviation = 0.080 (2) Å], making dihedral angles of 64.9 (1) and 66.4 (1)°. The pyrazine ring is perpendicular to the unit plane, with a dihedral angle of 89.0 (1)°. In the crystal, the complex mol­ecules are stacked in columns along the a axis and connected by C—H⋯Br hydrogen bonds, forming a helical chain along the b axis.
