A complex of nickel (11) with pyrazine-2,3,5,6-tetracarboxylic acid and 2,2'-bipyridine, [Ni(ptcH(2))(bpy) (H2O)], was synthesized by hydrothermal reaction of Ni (NO3)(2)center dot 6H(2)O with pyrazine-2,3,5,6-tetracarboxylic acid and 2,2'-bipyridine at 160 T and characterized by elemental analysis, IR and X-ray diffraction single crystal structure determined. The crystal belongs to Monoclinic system, with space group P2(1)/c, a= 1.327 9(7) nm, b = 1.279 7(7) nm, c = 1.1614(7) nm; beta= 113.435(8)degrees, V= 1. 810 6(17) nm(3), Z=4. The coordination environment of nickel(II) ion is a distorted octahedral geometry. The title complex is a mononuclear structure which is assembled into 3D supramolecular architecture by strong hydrogen bonds. CCDC: 661507.
