| Summary: | The PtII ion in the title complex, [PtCl2(C14H10N4)], 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 PtII 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.
