以硝酸锌、樟脑酸(H2CAM)和1,2.二咪唑基二甲苯(obix)或4,4'-二咪唑基二甲联苯(bimb)为原料.在水热条件下得到2个结构不同的配位聚合物[Zn(0bix)(CAM)]n(1)和[Zn(bimb)(CAM)]n(2).对它们进行了元素分析、红外光谱和热重等分析,并利用X-射线珩射测定了它们的单晶结构.配合物1中2个锌离子通过2个obix配体桥连成一个24元大环.它再通过CAM配体连接成一维管状结构,而配合物2中锌离子通过两种配体桥连成二维层状结构.结果说明了辅助配体在配合物组装过程中起着非常重要的作用.此外还研究了它们的荧光性质.%Two zinc coordination polymers:[zn(obix)(CAM)]n(1)and [Zn(bimb)(CAM)]n(2)(H2CAM=camphor acid,obix=1,2-bis (imidazo1-1-ylmethyl)benzene and bimb=4,4'-bis(imidazol-1-ylmethyl)biphenyl)have been synthesized under hydrothermal conditions and characterized by elemental analysis,IR spectroscopy,TGA and single-crystal X-ray diffraction.The crystal structures show that complex 1 crystallizes in triclinic,space group P1 with a=0.9734(3)nm,b=1.113 18(12)nm,c=1.2103(2)am,a=101.548(3)°,β=101.257(2)°,y=103.373(2)°,complex 2 crystallizes in monoclinic,space group P21/c with a=1.111 l(4)nm,b=1.4096(6)nm,c=1.7700(7)nm,wR2=O.1167.The bis(imidazole)ligands with different spacer lengths exhibit conformational flexibility and lead to the generation of diversified architectures.Complex 1 consists of 24-membered{Zn2(obix)2} tings that are furtherbridged by CAM anions into a one-dimensional tubular structure.Complex 2 shows a two-dimensional(2D)lattice network with(4,4)topology.Moreover,their luminescent properties have been investigated in the solid state.CCDC:796695,1;796696,2.
