In the title complex, [Co(C8H9N2O4)(2)(H2O)(2)]center dot 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 molecules in a distorted octahedral environment. The crystal structures features a three-dimensional network stabilized by extensive O-H center dot center dot center dot O and N-H center dot center dot center dot 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 molecules is located on a site with half-occupancy.
