Dibromido(2,3-di-2-pyridyl-pyrazine-?N,N)platinum(II).

ABSTRACT: 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-pyridyl-pyrazine 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 inter-molecular 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.
