In the title complex, [Cd(C8H9N2O4)(2)(H2O)(2)]center dot 3.5H(2)O, the Cd-II is coordinated by two water molecules and N,O-chelated by two 5-carboxy-2-propyl-1H-imidazole-4-carboxylate anions in a distorted octahedral geometry. The two imidazole rings are oriented to each other with a dihedral angle of 75.1 (2)degrees. Strong O-H center dot center dot center dot O hydrogen bonds between protonated and deprotonated carboxylate groups occur in the molecular structure. In the crystal structure extensive O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds help to stabilize the three-dimensional supramolecular framework. The propyl groups of anions are disordered over two sites with refined occupancies of 0.768 (6):0.232 (6) and 0.642 (8):0.358 (8).
