Tetraaqua(2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylato-²N³,O)cobalt(II) 2.5-hydrate

B. Sridhar and K. Ravikumar

Abstract: The Co^II ion in the title compound, [Co(C₅H₂N₂O₄)(H₂O)₄]·2.5H₂O, is chelated by the orotate dianion through carboxylate O and pyrimidine N atoms, and its octahedral geometry is completed by four water molecules. An intermolecular N-HO hydrogen bond forms an orotate-orotate dimer. An extensive three-dimensional hydrogen-bonded network of O-HO and N-HO bonds and weak - interaction [3.754 (2) Å] stabilize the crystal structure. One of the solvent water molecules is located on a twofold rotation axis.
