Abstract: The title complex, [Co(C₅H₂N₂O₄)(C₁₄H₈N₄)₂]·2H₂O, features a slightly distorted octahedral geometry for Co due to the sterical requirements of the orotic acid and pyrazino[2,3-f][1,10]phenanthroline ligands. Intermolecular hydrogen bonding between the uncoordinated water molecules and the ligand stablizes the structure of the complex.
