用水热法合成得到2个配合物,{[ML2(bipy)(H2O)2]· 2bipy}n(M=Cd 1,Zn 2；HL=3-羟基肉桂酸,bipy=4,4′-联吡啶),并对它们进行了红外分析、元素分析,热重分析和单晶结构分析.配合物1和2为异质同晶,单斜晶系,P2/c空间群.中心金属M为六配位,相邻的MⅡ通过4,4′-联吡啶桥联形成沿b轴延伸的一维链状结构,此外还存在未配位的4,4′-联吡啶作为客体分子位于链与链之间.通过对配合物1和2的固态荧光测试表明,它们在绿光区均显示发光效应.

Two linear structure metal-organic complexes,{[ML2(bipy)(H2O)2]·2bipy}n (M=Cd 1; Zn 2),based on 3-hydroxycinnamic acid (HL) and 4,4′-bipyridine (bipy) were synthesized and characterized by IR,elemental analyses,thermogravimetric analyses and X-ray diffraction technique.Two complexes are isostructural crystallized in monoclinic system,P2/c space group.The center metal ion is six-coordinated by two nitrogen atoms from the bridging bipy ligands,two oxygen atoms from two L ligands,and two water molecules,forming a distorted octahedral geometry.The MⅡ ions and bipy ligands link each other to form a 1D linear chain that infinitely propagates along b axis,and discrete bipy as guest molecules intersperses between the chains.The luminescent properties in the solid state and thermogravimetric analyses (TGA) of two complexes are also discussed.CCDC:818712,1;818713,2.
