Abstract: In the title compound, [Co(C₁₂H₈N₂)₂(H₂O)₂](C₅H₃N₂O₄)₂·2.25H₂O, the cobalt cation, located on a twofold axis, is coordinated by two symmetry-related aqua ligands together with a pair of symmetry-related bidentate phenanthroline (phen) molecules, and exhibits a distorted octahedral coordination. The unique orotate anion in the asymmetric unit has a single negative charge. The coordinated water molecules link the orotate ions to the metal complex via O-HO hydrogen bonds. Each uncoordinated water molecule is hydrogen bonded to orotate ions through O-HO hydrogen bonds.
