two-dimensional network structure of 1 and a double-stranded helical chain of 2. Complexes 4 and 5 also have helical chain structures with P and M forms. Differing from polymeric structure of 1, 2, 4 and 5, complexes 3 and 6 are a M2L2 molecular rectangle and a M4L2 cage, respectively. The results show that the flexible ligand L can have different conformation and coordination modes leading to complexes with varying
六个新的配位化合物[AgL] CF 3 SO 3(1和2),[Ag 2 L 2 ](NO 3)2 ·4CH 3 NO 2(3),[AgL] NO 3 ·0.5CH 3 OH(4),[AgL] BF 4(5)和[Cu 4 L 2(OCH 3)2(OH)2(NO 3)2 ](NO 3)2 ·0.32H 2 O(6),是通过相应的金属盐与配体反应获得的N,N'-双[4-(4,5-二氢恶唑-2-基)-苄基]乙烷-1,2-二胺(L)。X射线晶体学分析的结果表明,配合物1和2是超分子异构体,其波状阳离子二维网络结构为1,双链螺旋链为2。配合物4和5也具有螺旋链结构,P和M表格。从聚合结构不同1,2,4和5,复合物3和6是A M 2大号2分子矩形和A M 4大号2保持架,分别。结果表明,柔性配体L可以具有不同的构象和配位方式,从而形成具有不同结构的配合物。磁数据表明,在配合物6的二聚体单元中存在反铁磁相互作用。
