摘要 采用溶剂热法合成了2-(2-氨基苯)-1氢-苯并咪唑镍配合物NiL_2(H_2O)_2。利用元素分析、红外光谱和X-射线单晶衍射方法对配合物结构进行了表征。结构分析表明:配合物属于三斜晶系,空间群P-1,晶胞参数a()=9.3881(11),b()=10.7917(13),c()=15.3556(18),α(°)=94.957(2),β(°)=101.425(2),γ(°)=104.656(2),V(~3)=1459.9(3),Z=2。中心原子镍位于两个氧原子和四个氮原子形成的变形八面体中心,分子间通过O-H···Cl氢键形成二维层状结构。热重分析表明该配合物具有较高的热稳定性。 One complex named Ni ( apbi ) 2 ( H2 0 ) 2 ( apbi = 2- ( 2-Aminophenyl ) -1 H-benzimidazole ) was synthesized under hydrothermal conditions and characterized by Elemental Analysis, IR spectroscopy and X-ray diffraction. The results show that the title complex crystallizes in triclinicwith space group P - 1, a (A) =9. 3881 (11),b(A) = 10. 7917(13),c(A) = 15. 3556(18),α(°) =94. 957(2), β(°) = 101. 425 (2) ,γ(°) = 104. 656(2) ,V( A3 ) = 1459.9 (3) ,Z = 2. Complex forms a two-dimensional layer structure through the intermolecular 0 -H..-C1 hydrogen bond interacting between the coordinated wa- ters and the uncoordinated chloridion. Thermogravimetric higher than that of the li^and. Analysis shows that the stability of complex is higher than that of the ligand.
