(2,3-Di-2-pyridyl-pyrazine-?N,N)diiodidopalladium(II).

ABSTRACT: The Pd(II) ion in the title complex, [PdI(2)(C(14)H(10)N(4))], is four-coordinated in a slightly distorted square-planar environment by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl-pyrazine (dpp) ligand and two iodide anions. In the crystal, the pyridine rings are considerably inclined to the least-squares plane of the PdI(2)N(2) unit [maximum deviation = 0.090?(2)?Å], making dihedral angles of 65.0?(2) and 66.6?(2)°. The pyrazine ring is perpendicular to the unit plane, with a dihedral angle of 89.9?(2)°. The complex mol-ecules are connected by C-H?I hydrogen bonds, forming a helical chain along the b axis.
