The dinuclear copper complex [Cu2 (C8H3NO6) 2 (C10H8N2) (H2O) 2] 2H2O (C8H3NO6) was obtained by the reaction of 3-nitrophthalic acid and 2,2’-bipyridine with copper nitrate in aqueous ethanol = 3-nitrophthalate, C10H8N2 = 2,2’-bipyridyl) were synthesized and characterized by IR and elemental analysis.The results of X-ray diffraction showed that the crystal belongs to triclinic system, space group (3) nm, α = 87.835 (2) °, β = 74.911 (3) °, β = 74.911 (3) ° for the P-1 crystallographic parameters of a = 0.7534 (19) nm and b = 1.0467 = 77.437 (3) °, V = 0.8949 (4) nm3, Z = 1, Dc = 1.725g / cm3, μ = 1.277mm- 1, F (000) = 474, R = The coordinative atoms are arranged in a quadrangular pyramid around the copper ions, and the two asymmetric coordination units in a centrosymmetric relationship are connected by Cu-O bonds to form dimers. The discrete complex molecules are separated by intermolecular hydrogen bonds and CH ... π and other supermolecules weak interaction force to build and stabilize the space three-dimensional network structure.
