(2,3-Di-2-pyridylpyrazine-κ2N2,N3)bis(thiocyanato-κS)palladium(II)

The Pd-II ion in the title complex, [Pd(NCS)(2)(C14H10N4)], is four-coordinated in a distorted square-planar environment by the two pyridine N atoms of the chelating 2,3-di-2-pyridylpyrazine (dpp) ligand and two S atoms from two thiocyanate anions. The pyridine rings are considerably inclined to the least-squares plane of the PdS2N2 unit [maximum deviation = 0.027 (1) angstrom], making dihedral angles of 70.3 (2) and 69.2 (1)degrees. The pyrazine ring is almost perpendicular to the PdS2N2 plane, with a dihedral angle of 86.3 (1)degrees. The thiocyanate ligands are located on opposite sides of the PdS2N2 unit plane and are almost linear [N-C-S angles = 177.8 (6) and 178.9 (6)degrees]. The complex molecules are stacked in columns along the b axis and are connected by intermolecular C-H center dot center dot center dot N hydrogen bonds, forming chains along the a axis.
