Abstract：

Two new coordination polymers {[Zn(Hbtc)(bpyb)]•H2O}n (1) and {[Cd(Hbtc)- (bpyb)1.5]•0.5bpyb}n (2) (H3btc = 1,3,5-benzenetricarboxylic acid, bpyb = 1,4-bis(4-pyri- dyl)benzene) have been synthesized under hydrothermal conditions. The two compounds were characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Compound 1 displays a 2-fold interpenetrating 3D supramolecular architecture through O–H•••N/O hydrogen bonds and π-π stacking interactions. Compound 2 exhibits a 2D→3D polycatenated structure, which is further stabilized by O–H•••N hydrogen bonds. The results indicate that the metal ion has significant effects on the formation and structure of the resulted coordination polymers. Furthermore, thermal stability and photoluminescent properties of 1 and 2 are also discussed in detail.

Key words： Zn(II)/Cd(II) 1,3,5-benzenetricarboxylic acid photoluminescent properties
