摘要

Two main group coordination polymers based on 2-(2-pyridyl)-4,5-imidazole-dicarboxylic acid (H(3)oPyIDC), namely [ Ba(H(2)oPyIDC)(2)(H2O)](n) (1) and [ Pb-2(HoPyIDC)(2)](n) (2) are obtained under hydrothermal conditions. In compound 1, the Ba2+ cations and HoPyIDC2- anions are connected to a 1D chain, and the 1D chains are further interconnected by Ba-O bonds, forming a 3D 3-connected framework. In compound 2, a 2D layer with (4,4) topology is formed by Pb-II ions and HoPyIDC2- anions. The 2D layer are pillared by HoPyIDC2-, yielding a 3D (3,4)-connected framework. The thermogravimetric analyses and luminescence properties of compounds 1 and 2 are also investigated.
