A systematic investigation into the reactions of o- and p-phenylenediacetic acid with zinc(II) and cadmium(II) salts in the presence of the semi-rigid 1,4-bis(2-methylimidazol-1-ylmethyl)benzene (pbmeix) co-ligand is reported. Five new coordination polymers – [Zn(μ-opda)(μ-pbmeix)_0.5]_n1, {[Zn(μ-ppda)(μ-pbmeix)]·H₂O}_n2, {[Zn(μ-ppda)(μ-pbmeix)]∙0.5pbmeix∙H₂O}_n3, {[Cd(μ-opda)(μ-pbmeix)]·0.5DMF}_n4 and [Cd(μ-ppda)(μ-pbmeix)_0.5]_n5 (o/ppda = 1,2-/1,4-phenylenediacetate) – have been prepared and structurally characterised. Compounds 1 and 5 were found to form three-dimensional coordination networks, 2 forms a two-dimensional structure whereas both 3 and 4 form one-dimensional nanotubular structures. Compounds 1 and 4 are opda complexes in which the dicarboxylate shows a tridentate coordination mode in 1 and a tetradentate coordination mode in 4. Compounds 2, 3 and 5 are ppda complexes in which the dicarboxylate adopts bidentate (2, 3) and hexadentate (5) coordination modes. The structure of 2 contains interpenetrated 2D frameworks and is a polycatenane with ppda linkers from one framework passing through Zn₂(μ-pbmeix)₂ rings from a neighbouring framework. The thermal stability of complexes 1–4 and luminescence properties of complexes 1 and 4 are also reported.

在半刚性1,4-双（2-甲基咪唑-1-基甲基）苯（pbmeix ）存在下，邻和对苯二乙酸与锌（II）和镉（II）盐反应的系统研究）共配体被报道。五个新的配位聚合物– [Zn（μ-opda）（μ-pbmeix）_0.5 ] _n 1，{[Zn（μ-ppda）（μ-pbmeix）]·H ₂ O} _n 2，{[Zn（μ- ppda）（μ-pbmeix）]∙0.5pbmeix∙H ₂ O} _n 3，{[Cd（μ-opda）（μ-pbmeix）]·0.5DMF} _n 4和[Cd（μ-ppda）（μ- pbmeix）_0.5 ] _n 5（o / ppda = 1,2- / 1,4-苯二乙酸酯）–已制备并进行了结构表征。发现化合物1和5形成三维配位网络，化合物2形成二维结构，而化合物3和4都形成一维纳米管结构。化合物1和4是opda络合物，其中二羧酸盐在1中显示为三齿配位模式，在4中显示为四齿配位模式。化合物2，3和5是PPDA络合物，其中二羧酸二齿采用（2，3）和hexadentate（5）协调模式。2的结构包含互穿的2D框架，是带有一个ppda接头的聚环丁烷，该ppda接头来自一个框架，并穿过一个相邻框架的Zn ₂（μ-pbmeix）₂环。配合物的热稳定性1 - 4和配合物的发光特性1和4也报告。
