In the title complex, [Zn(C8H9N2O4)(2)(H2O)(2)]center dot 3.5H(2)O, the Zn-II ion is coordinated by two N,O-bidentate H(2)pimda ligands (H(3)pimda = 2-propyl-1H-imidazole-4,5-dicarboxylic acid) and two water molecules in a distorted octahedral environment. In the crystal structure, extensive intermolecular O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds stabilize the three-dimensional supramolecular network. Intramolecular O-H center dot center dot center dot O hydrogen bonds between the carboxyl groups are also observed. The propyl groups of the two H(2)pimda ligands are disordered each over two sites, with occupancy factors of 0.752 (5):0.248 (5) and 0.519 (7):0.481 (7). One of the water molecules is half-occupied.
