A new copper(II) complex [Cu2(DMF)(H2O)(C7H4NO4)2(C7H3NO4)]2·3.5DMF has been synthesized and its structure was determined by single-crystal X-ray diffraction.The crystal is of triclinic,space group P1 with a = 10.722(3),b = 18.170(4),c = 20.923(7),α = 105.297(9),β = 101.701(10),γ = 105.74(1)°,V = 3615(1) 3,Z = 2,C58.50H64.50Cu4N11.50O31.50,Mr = 1686.90,Dc = 1.550 g/cm3,μ = 1.255 mm-1,F(000) = 1728.00,T = 150(2) K,the final R = 0.0640 and wR = 0.173 for 11310 observed reflections with I > 2σ(I).In the crystal,each formular unit consists of two dinuclear copper(II) compounds,between which the O-H···O hydrogen bonds exist.Each CuII cation is six-coordinated in an octahedral geometry.The intermolecular hydrogen-bonding interaction leads to a 3-D framework of the title compound.
