Özet
The Co-II ion in the title complex {[ Co(C5H2N2O4)( H2O)(3)] -1.72H(2)O} n, has a distorted octahedral coordination geometry comprised of three water ligands, one deprotonated pyrimidine N atom and an adjacent carboxylate O atom of one orotate ligand. The sixth coordination site is occupied by an exocyclic O atom from a neighbouring orotate moiety, and through this interaction a helicoidal chain is formed. The molecules are linked by intramolecular O-water - H center dot center dot center dot O and intermolecular N - H center dot center dot center dot O and O-water - H center dot center dot center dot O hydrogen bonds, forming a three- dimensional network.
