摘要：
The title complex, [Cd-2(NO3)(4)(C24H16N6)(CH4O)(2)], displays a centrosymmetric dinuclear structure, in which the 2,3,5,6-tetra- 2-pyridinylpyrazine (tppz) ligand links two Cd ions separated by 7.323 (4) angstrom. Each Cd-II center is seven-coordinated by three N-atom donors of tppz in one plane, by two O atoms nearly normal to this plane, and by two O atoms 0.393 (3) and 0.488 (3) angstrom from that plane. The two Cd-II ions are above and below the plane of the pyrazine ring of the tppz ligand, oriented with respect to the pyridine rings at dihedral angles of 38.01 (3) and 31.90 (3)degrees. The dihedral angle between the two pyridine rings is 41.11 (3)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O hydrogen bonds link the molecules.
