【摘要】 Two new compounds,1([Cu(IDB2]Cl2·2CH3CH2OH·2H2O(IDB = N,N-di(2-benzimidazolylmethyl)imine]) and 2([Cu(EDTB)]·2[C6H4(OH)COO]·6H2O(EDTB = N,N,N’,N’-tetrakis-[(2-benzimidazolyl)methyl]-1,2-ethanediamine]),have been synthesized and their crystal structures were determined by single-crystal X-ray diffraction. Crystal 1 belongs to the triclinic system,space group P1 with a = 9.565(2),b = 9.863(2),c = 10.252(3) ?,α = 81.915,β = 88.330,γ = 87.347°,V = 956.28(40) ?3,Z = 1,F(000) = 427,Dc = 1.419 g/cm3,Mr = 817.27 and μ(MoKα) = 0.764 mm-1. The final R indices(I > 2σ(I)): R = 0.0505,wR = 0.1417; R indices(all data): R = 0.0591,wR = 0.1525. Crystal 2 is of triclinic system,space group P1 with a = 11.487(3),b = 13.396(4),c = 17.977(5) ?,α = 73.899(5),β = 86.629(5),γ = 65.018(4)°,V = 2403.8(12) ?3,Z = 2,F(000) = 1072,D3c = 1.417 g/cm,Mr = 1025.54,μ(MoKα) = 0.528 mm-1. The final R indices(I > 2σ(I)): R = 0.0769,w R = 0.163 2; R indices(all data): R = 0.0769,wR = 0.1632. The two compounds exhibit mononuclear structures. The copper(Ⅱ) atom of crystal 1 is six-coordinated by four nitrogen atoms of benzimidazole groups and two amine nitrogen atoms from the ligand IDB to adopt a distorted octahedral coordination geometry. The copper(Ⅱ) atom of crystal 2 is six-coordinated by four nitrogen atoms of benzimidazole groups and two amine nitrogen atoms from the ligand EDTB to show a distorted octahedral coordination geometry. Particularly,the two compounds exhibit fluorescent properties at room temperature in ethanol.
