Two main group coordination polymers based on 2‐(2‐pyridyl)‐4,5‐imidazole‐dicarboxylic acid (H 3 o PyIDC), namely [Ba(H 2 o PyIDC) 2 (H 2 O)] n ( 1 ) and [Pb 2 (H o PyIDC) 2 ] n ( 2 ) are obtained under hydrothermal conditions. In compound 1 , the Ba 2+ cations and HoPyIDC 2– 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 HoPyIDC 2– anions. The 2D layer are pillared by HoPyIDC 2– , yielding a 3D (3,4)‐connected framework. The thermogravimetric analyses and luminescence properties of compounds 1 and 2 are also investigated.
