Dichlorido(2,3-di-2-pyridyl­pyrazine-κ(2) N (1),N (2))platinum(II)

The Pt(II) ion in the title complex, [PtCl(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-pyridyl­pyrazine ligand and two chloride anions. The pyridyl ring coordinated to the Pt(II) atom is inclined slightly to its carrier pyrazine ring [dihedral angle = 13.5 (1)°], whereas the uncoordinated pyridyl ring is inclined considerably to the pyrazine ring [dihedral angle = 54.3 (2)°]. The dihedral angle between the two pyridyl rings is 59.2 (2)°. In the crystal, the complexes are assembled through inter­molecular C—H⋯N and C—H⋯Cl hydrogen bonds, forming a three-dimensional network. Intra­molecular C—H⋯N and C—H⋯Cl hydrogen bonds are also present.
