本文报道了三种新的铋系有机化合物Bi（OH）（2，6-pdc）·H（2）O（1），Bi（4）（OH）（4）（2，6-pdc）（4）（H（2）O）（3）·H（2）O（2）和Bi（5）（OH）（5）（2，6-pdc）（5）（H（2）O）（4）·H（2）O（3）（2，6-H（2）pdc =吡啶-2，6-二羧酸酯）已经通过在水热条件下引入不同的Bi亚基作为结构单元而获得。化合物1含有二聚{Bi（2）}单元，并且这些单元进一步通过2，6-pdc（2-）配体连接成具有3（6）拓扑的2D网络。化合物2-3通过分别使用线性{Bi（8）}和{Bi（10）}作为二级结构单元（SBU）而显示4（4）网络拓扑。化合物1-3分别显示黄色和蓝色发光。此外，还研究了1-3的PXRD、TGA、紫外-可见和红外光谱。
Three new bismuth-organic compounds, namely, Bi(OH)(2,6-pdc)·H(2)O (1), Bi(4)(OH)(4)(2,6-pdc)(4)(H(2)O)(3)·H(2)O (2) and Bi(5)(OH)(5)(2,6-pdc)(5)(H(2)O)(4)·H(2)O (3) (2,6-H(2)pdc = pyridine-2,6-dicarboxylate) have been obtained by incorporating different Bi subunits as building blocks under hydrothermal conditions. Compound 1 contains dimeric {Bi(2)} units and these are further linked by 2,6-pdc(2-) ligands into a 2D net with 3(6) topology. Compounds 2-3 display 4(4) net topology by using linear {Bi(8)} and {Bi(10)} as secondary building units (SBUs), respectively. Compounds 1-3 display yellow and blue luminescence, respectively. Furthermore, the PXRD, TGA, UV-visible and IR spectra of 1-3 were also studied.
