Dichlorido(2,3-di-2-pyridyl-pyrazine-?N,N)palladium(II).

ABSTRACT: The Pd(II) ion in the title complex, [PdCl(2)(C(14)H(10)N(4))], has a slightly distorted square-planar environment defined by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl-pyrazine ligand and two chloride anions. The pyridine rings are considerably inclined to the least-squares plane of the PdCl(2)N(2) unit [maximum deviation = 0.073?(1)?Å], with dihedral angles of 64.19?(9) and 66.55?(9)°. The pyrazine ring is almost perpendicular to this plane and the dihedral angle is 88.2?(1)°. Two independent inter-molecular C-H?Cl hydrogen bonds, both involving the same Cl atom as a hydrogen-bond acceptor, give rise to chains running along the a and b axes, generating a layer structure extending parallel to (001). Mol-ecules are stacked in columns along the a axis. Along the b axis, successive mol-ecules stack in opposite directions.
