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

ABSTRACT: The Pt(II) ion in the title complex, [PtI(2)(C(14)H(10)N(4))], exists in a distorted square-planar environment defined by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl-pyrazine ligand and two iodide anions. The pyridine rings are inclined to the least-squares plane of the PtI(2)N(2) unit [maximum deviation = 0.070?(3)?Å] at 66.1?(2) and 65.9?(2)°; the pyrazine ring is perpendicular to this plane [dihedral angle = 89.7?(2)°]. Two inter-molecular C-H?I hydrogen bonds, both involving the same I atom as hydrogen-bond acceptor, generate 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.
