以两个结构相近但具有不同氢键受体的取代苯甲酸盐作为辅助配体,合成了3个叠氮铜配合物,[Cu(L1)(N3)(H2O)]n(1),[Cu(L1)(N3)(MeOH)]n(2)和[CuL2HL2(N3)3(H2O)]n(3)(HL1=4-硝基苯甲酸;HL2=2-苯基-4-喹啉甲酸),并研究了它们的结构与磁性.配合物1是一个羧酸/EO-叠氮桥联的铜链,并由氢键连成三维结构;配合物2是同配合物1相似的链状结构,但是由氢键连成了二维结构;配合物3是一个具有三重氢键的三维超分子网络.磁性研究表明在配合物1和3中存在铁磁耦合作用.
Three azide copper complexes [Cu (L1) (N3) (H2O)] n (1) were synthesized by using two substituted benzoates with similar structure but different hydrogen bond acceptors as auxiliary ligands. (HL1 = 4-nitrobenzoic acid; HL2 = 2-phenyl-4- (4-nitrobenzoic acid) Quinolinecarboxylic acid) were synthesized and their structures and magnetic properties were studied. Complex 1 was a carboxylic acid / EO-azide bridged copper chain and was hydrogen bonded to a three-dimensional structure. Complex 2 was similar to that of complex 1 Chain structure, but the two-dimensional structure was formed by hydrogen bonding and that the complex 3 was a three-dimensional supramolecular network with triple hydrogen bonds.The magnetic study showed that there was ferromagnetic coupling in complexes 1 and 3.
