A series of new coordination polymers, namely, [Sr(H 2 EIDC) 2 (H 2 O) 2 ] n ( 1 ),{[Pb(H 2 EIDC) 2 (H 2 O)](H 2 O) 3 } n ( 2 ), [Ag(H 2 EIDC)] n ( 3 ), and [Ba(H 2 EIDC) 2 (H 2 O)] n ( 4 ) (H 2 EIDC = 2‐ethyl‐1H‐imidazole‐4,5‐dicarboxylate), were synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectroscopy, X‐ray diffraction and thermogravimetric analyses. Complex 1 is a 2D infinite gridlike (4,4)topological layer structure. Complex 2 is a 2D corrugated layer constructed by Pb II atoms and H 2 EIDC – anions. Complex 3 is a 2D corrugated sheet consisting of 1D chains linked by short Ag ··· Ag interactions, and the three complexes are extended into 3D supramolecular structures by weak intermolecular forces such as hydrogen bonds and π–π stacking interactions. Complex 4 exhibits a 3D framework with 1D channels. Furthermore, the luminescent properties of complexes 1 , 2 , and 3 are also investigated.
