Dichlorido(2,3-di-2-pyridyl-pyrazine-κN,N)palladium(II).
The Pd(II) ion in the title complex, [PdCl(2)(C(14)H(10)N(4))], is four-coordinated in a distorted square-planar environment defined by two N atoms of a chelating 2,3-di-2-pyridyl-pyrazine (dpp) ligand and two chloride anions. The pyridine ring coordinated to the Pd atom is inclined slightly to its carrier pyrazine ring [dihedral angle = 14.4 (3)°], whereas the uncoordinated pyridine ring is inclined considerably to the pyrazine ring [dihedral angle = 52.2 (2)°]. The dihedral angle between the two pyridine rings is 58.8 (2)°. In the crystal, complex mol-ecules are connected by inter-molecular C-H⋯Cl and C-H⋯N hydrogen bonds, forming a three-dimensional network. Intra-molecular C-H⋯Cl hydrogen bonds are also present.
