title: Diaqua-bis-(5-carb-oxy-2-propyl-1H-imidazole-4-carboxyl-ato-κN,O)cobalt(II) 3.5-hydrate.
abstract: In the title complex, [Co(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·3.5H(2)O, the Co(II) cation is six-coordinated by two H(2)pimda(-) ligands (H(3)pimda is 2-propyl-1H-imidazole-4,5-carboxylic acid) and two water mol-ecules in a distorted octa-hedral environment. The crystal structures features a three-dimensional network stabilized by extensive O-H⋯O and N-H⋯O hydrogen bonds. The propyl groups of the ligands are disordered over two sets of sites with refined occupancies of 0.673 (8):0.327 (8) and 0.621 (17):0.379 (17). One of the water mol-ecules is located on a site with half-occupancy.
