Abstract
The PdII ion in the title complex, [PdCl2(C14H10N4)], is four-coordinated in a distorted square-planar environment defined by two N atoms of a chelating 2,3-di-2-pyridylpyrazine (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 molecules are connected by intermolecular C—H⋯Cl and C—H⋯N hydrogen bonds, forming a three-dimensional network. Intramolecular C—H⋯Cl hydrogen bonds are also present.
