✦ Synopsis

The Co II ion in the title compound, [Co(C 5 H 2 N 2 O 4 )(H 2 O) 4 ]Á-2.5H 2 O, 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-HÁ Á ÁO hydrogen bond forms an orotate-orotate dimer. An extensive three-dimensional hydrogen-bonded network of O-HÁ Á ÁO and N-HÁ Á ÁO bonds and weakinteraction [3.754 (2) A ˚] stabilize the crystal structure. One of the solvent water molecules is located on a twofold rotation axis.
