| Abstract: | Two main group coordination polymers based on 2‐(2‐pyridyl)‐4,5‐imidazole‐dicarboxylic acid (H3oPyIDC), namely Ba(H2oPyIDC)2(H2O)]n ( 1 ) and Pb2(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 PbII 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. |
