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))], is four-coordinated in a distorted square-planar environment by two N atoms of a chelating 2,3-di-2-pyridyl-pyrazine ligand and two bromide anions. In the crystal, the pyridyl ring coordinated to the Pt atom is inclined slightly to its carrier pyrazine ring [dihedral angle = 14.7?(2)°], whereas the uncoordinated pyridyl ring is inclined considerably to the pyrazine ring [dihedral angle = 51.9?(3)°]. The dihedral angle between the two pyridyl rings is 57.7?(3)°. Two complex mol-ecules are assembled through inter-molecular C-H?N hydrogen bonds, forming a dimer-type species. Intra-molecular C-H?Br and C-H?N hydrogen bonds are also present.
