报道三齿配体N,N-二(2-苯并咪唑甲基)亚胺(IDB)及单核镍(Ⅱ)配合物[Ni(IDB)_2][C_6H_4(OH)COO]·ClO_4·CH_3CH_2OH·H_2O的合成、晶体结构和催化尿素水解活性。该配合物为三斜晶系，P1空间群，a=1.1010(2) nm，b=1.3800(3) nm，c=1.5550(3) nm，α=100.75(3)°，β=102.97(3)°，γ=107.56(3)°，V=2.1113(7) nm~3，Z=2，F(000)=952，D_c=1.438g/cm~3，M_r=914.01，μ=0.591 mm~-~1。最终因子R[I>2σ(I)]:R_1=0.0591，ωR_2=0.1325；R(全部数据)：R_1=0.1302，ωR_2=0.1572。结构分析表明，镍(Ⅱ)分别与两个配体中的四个苯并咪唑氮和两个亚胺基氮配位形成畸变的八面体构型。用气相色谱仪测定配...

The title complex [Ni(IDB)(2)] [C6H4(OH)COO]. ClO4. CH3CH2OH .H2O [IDB = N,N-di(2-benzimidazolylmethyl) imine] has been synthesized and characterized by elemental analysis, IR and UV - Vis spectra The crystal structure has been determined by single crystal X-ray diffraction. The crystal of mononuclear Ni(II) complex is triclinic system, space group, P (1) over bar, a = 1.1010(2)nm, b = 1.3800(3)nm, c=1.5550(3)nm, alpha = 100.75(3)degrees, beta = 102.97(3)degrees, gamma = 107.56(3)degrees, V = 2.1113(7)nm(3), Z = 2, F(000) = 952, D-c = 1.438g/cm(3), M-r = 914.01, mu = 0.591mm(-1).
