mer-Diaqua­bis(1H-imidazole-[kappa]N³)[orotato(2-)]cobalt(II)

In the title complex, mer-diaqua[2,6-dioxo-1,2,3,6-tetra­hydropyrimidine-4-carboxyl­ato(2-)]­bis(1H-imidazole-[kappa]N³)cobalt(II), [Co(C₅H₂N₂O₄)(C₃H₄N₂)₂(H₂O)₂], the Co^II ion is coordinated by a deprotonated N atom and the carboxyl­ate O atom of the orotate ligand, two imidazole N atoms and two aqua ligands in a distorted octa­hedral geometry. The title complex exists as discrete doubly hydrogen-bonded dimers, and a three-dimensional network of O-H...O and N-H...O hydrogen bonds and weak [pi]-[pi] inter­actions is responsible for crystal stabilization.
