摘　　要：水热合成了2个以D-樟脑酸(D-H2cam)与1,4-二(咪唑-1-基)丁烷(1,4-bimb)为配体的配位聚合物:[Co(D-cam)(1,4-bimb)]n·4nH2O(1)和[Ni(D-cam)(1,4-bimb)]n(2)。通过X-射线单晶衍射,元素分析,红外光谱,XRD分析,热重,和磁性分析对其结构进行了表征。测定了这两个聚合物的磁性。结构分析表明,1为P2空间群,其链状结构由氢键作用连接形成二维结构;2为Pna21空间群,呈四重穿插的dia网络结构。Two new coordination polymers, [Co（D-cam）（1,4-bimb）]n·4nH2O（1）, [Ni（D-cam）（1,4-bimb）]n（2）（DH2cam=D-camphoric acid, 1,4-bimb=1,4-bis（imidazol）-butane） have been prepared under hydrothermal conditions.X-ray crystal structure analyses reveal that coordination polymers 1 and 2 display different topology structures and properties controlled by variable coordination positions and conformations of the ligands. 1 crystallizes in the chiral P2 space group and shows a 1D double chain in which 1,4-bimb ligands exhibit the asymmetrical TTG conformation. 2 crystallizes in the chiral Pna21 space group and shows a four fold interpenetrating dia net topology in which 1,4-bimb ligands adopt the symmetrical GTG conformation. Moreover, the magnetic properties of polymers 1 and 2 were measured. CCDC： 894190, 1; 894191, 2.
