| 摘 要： | A novel dinuclear copper(Ⅱ) complex CuL(NO3)]2·2MeOH was obtained by the coordination reaction of Cu(NO3)2·3H2O with ligand HL (HL=N-(methyl-2-benzimidazol- methylidene)-2-hydroxyaniline). The single-crystal X-ray analysis has revealed that the complex crystallizes in triclinic, space group P with a=9.535(3), b=10.009(3), c=10.666(4) , α=104.303(4), β=100.105(4), γ=115.917(4)o, V=839.0(5) 3, C16H16CuN4O5, Mr=407.87, Z=2, Dc=1.614 g/cm3, F(000)=418, μ=1.338 mm-1, R=0.0543 and wR=0.0980. The basic dinuclear copper(Ⅱ) complex units CuL(NO3)]2 are formed by NO3- as co-bridging ligands and L as NNO tridentate chelate coordinating to the copper ions. The ladder-like one-dimensional chain motifs are formed by O…H-O and O…H-N hydrogen bonds from methanol molecules connecting the dinuclear copper(Ⅱ) units.
