In this study, a novel open-framework binuclear zinc carboxylate, Zn<sub>2</sub>(C<sub>21</sub>H<sub>9</sub>NO<sub>8</sub>)(H<sub>2</sub>O) (compound 1), was constructed from 1, 3-di(3', 5'-dicarboxylphenyl)pyridine (H<sub>4</sub>L) with the transition metal zinc under DMA/CH<sub>3</sub>CN/H<sub>2</sub>O mixed solvothermal conditions. Single-crystal X-ray diffraction analysis revealed that compound 1 crystallized in the orthorhombic space group P2<sub>1</sub>2<sub>1</sub>2<sub>1</sub> (No.19). The oxygen atoms in carboxylate chelated with Zn to form a secondary building unit (SBU) featuring binuclear zinc, and these SBUs were constructed by H<sub>4</sub>L further into the open-frameworks of compound 1 featuring extra-large channels along y axis %K 有机羧酸配体 %K 溶剂热合成 %K 双核锌羧酸配合物 %K 超大孔道< %K br> %K organic carboxylate %K solvothermal synthesis %K binuclear zinc carboxylate frameworks %K extra-large channel %U http://xbgjxt.swu.edu.cn/jsuns/html/jsuns/2017/11/201711015.htm
