摘　　要：利用合成的两性离子二酸配体1-(4-carboxylatobenzyl)pyridinium-4-carboxylate(HL),通过调变合成条件,制备了2个低维的配合物{Cd(L)2·4H2O}n(1),和{[Cd(L)(N3)]·3H2O}n(2),并对其进行了元素分析(EA)、红外光谱(IR)、热重(TG)、荧光光谱及X-射线单晶衍射测定。分析结果显示化合物1中八配位的Cd(Ⅱ)离子被4个L配体连接形成一维链状结构。而化合物2中六配位的Cd(Ⅱ)离子被双羧基-叠氮三重桥联形成二维层状结构。固体荧光测试表明配体的配位方式明显影响其荧光发射。By controllable syntheses, two low dimensional Cd （Ⅱ） complexes with the newly zwitterionicdicarboxylate ligand 1-（4-carboxylatobenzyl）pyridinium-4-carboxylate （HL） {Cd（L）2·4H2O}n（1）, and {[Cd（L）（N3）]·3H2O}n（2） （2） have been synthesized and structurally characterized by [R, elemental analyses, single-crystal X-raydiffraction. In compound 1, the eight-coordinated Cd（Ⅱ） ions are chelated by four equivalent L in a bis（chelating）mode, forming a one-dimensional coordination polymer structure. In 2, six-coordinated Cd （Ⅱ） ions are triplebridged by two carboxylate groups and an azide ion into 1D uniform [Cd（N3）（OCO）2]n chains, which are furtherinterlinked through the cationic N-benzylpyridinium backbones of the L ligands into 2D sheet. Interestingly, thefluorescence measurements show that all compounds exhibit intense blue emission in the solid state, and theemission bands are correlated to the coordination modes of the L ligand.
