摘要

The PtII ion in the title complex, PtI2(C14H10N4), exists in a distorted square-planar environment defined by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl­pyrazine ligand and two iodide anions. The pyridine rings are inclined to the least-squares plane of the PtI2N2 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 inter­molecular C—H⋯I hydrogen bonds, both involving the same I atom as hydrogen-bond acceptor, generate a layer structure extending parallel to (001). Mol­ecules are stacked in columns along the a axis. Along the b axis, successive mol­ecules stack in opposite directions.
