1、第29卷第10期无机化学学报Vo1.29No.102013年10月CHINESEJOURNALOFINORGANICCHEMISTRY2251—2256樟脑酸根及双咪唑基配体构筑的镉(Ⅱ)配位聚合物的合成、晶体结构及荧光性质刘光祥(南京晓庄学院生物化工与环境工程学院,南京211171)摘要:以硝酸镉,樟脑酸(HzCAM)~I1,3,5--(1一咪唑基一亚甲基)一2,4,6一三甲基苯(titmb)为原料,采用水热合成的方法得到了一个三维配位聚合物([Cd2(titmb)(CAM)2]·2H20}。通过元素分析、红外光谱以及X.射线单晶’珩射对
2、其进行了表征。该晶体属三斜晶系,PT~_N。Cd(Ⅱ)离子通过CAM配体桥联形成一维链状结构,链与链再通过titmb配体连接成新型三维(4.64.8)(4z.6.89)(6z.8)拓扑的结构。室温下该配合物表现出较强的荧光发射。关键词:镉配合物;水热合成;晶体结构;荧光性质中图分类号:0614.24+2文献标识码:A文章编号:1001—4861(2013)10—2251.06DOI:10.3969~.issn.1001—4861.2013.00.210Synthesis,CrystalStructureandFluorescentPrope
