| 摘要: 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。 |

| Abstract: 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. |
