Diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-κ²N³,O⁴)cobalt(II) 3.5-hydrate

Abstract

In the title complex, [Co(C8H9N2O4)2(H2O)2]·3.5H2O, the CoII cation is six-coordinated by two H2pimda− ligands (H3pimda 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⋯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 mol­ecules is located on a site with half-occupancy.
