Abstract

Two novel zinc(II) coordination polymers, namely [Zn2(ptca)(OH)(bpe)(H2O)]n (1) and {[Zn(Hptca)(bpa)]·H2O}n (2) (H3ptca is 1,3,5-pentanetricarboxylic acid, bpe is 1,2-bis(4-pyridinyl)ethylene, bpa is 1,2-bis(4-pyridinyl)ethane) have been prepared through solvothermal reactions. Single-crystal X-ray diffraction revealed that both complexes 1 and 2 have two-dimensional layer structures pillared by nitrogen-donor ligands, wherein different degrees of deprotonation and coordination modes of carboxylate groups are observed. In addition, the fluorescent properties of complexes 1 and 2 have been studied in the solid state at room temperature.
