title: (2,3-Di-2-pyridyl-pyrazine-κN,N)bis-(thio-cyanato-κS)palladium(II).
abstract: The Pd(II) ion in the title complex, [Pd(NCS)(2)(C(14)H(10)N(4))], is four-coordinated in a distorted square-planar environment by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl-pyrazine (dpp) ligand and two S atoms from two thio-cyanate anions. The pyridine rings are considerably inclined to the least-squares plane of the PdS(2)N(2) unit [maximum deviation = 0.027 (1) Å], making dihedral angles of 70.3 (2) and 69.2 (1)°. The pyrazine ring is almost perpendicular to the PdS(2)N(2) plane, with a dihedral angle of 86.3 (1)°. The thio-cyanate ligands are located on opposite sides of the PdS(2)N(2) unit plane and are almost linear [N-C-S angles = 177.8 (6) and 178.9 (6)°]. The complex mol-ecules are stacked in columns along the b axis and are connected by inter-molecular C-H⋯N hydrogen bonds, forming chains along the a axis.
