Catena-Poly[[[triaquacobalt(II)]-μ-2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylato(2–)] 1.72-hydrate

Abstract

The Co(II) ion in the title complex {[Co(C5H2N2O4)(H2O)3].1.72H2O}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 Owater-H...O and intermolecular N-H...O and Owater-H...O hydrogen bonds, forming a three-dimensional network.
