title: Diaqua-bis-(5-carb-oxy-2-propyl-1H-imidazole-4-carboxyl-ato-κN,O)zinc(II) 3.5-hydrate.
abstract: In the title complex, [Zn(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·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-dicarb-oxy-lic acid) and two water mol-ecules in a distorted octa-hedral environment. In the crystal structure, extensive inter-molecular O-H⋯O and N-H⋯O hydrogen bonds stabilize the three-dimensional supra-molecular network. Intra-molecular O-H⋯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 mol-ecules is half-occupied.
