Abstract: The title compound [systematic name: bis(2,5-dioxo-4,4-diphenylimidazolidin-1-ido-N¹)bis(ethylenediamine-²N,N')cobalt(II)], [Co(C₁₅H₁₁N₂O₂)₂(C₂H₈N₂)₂], has site symmetry . The Co^II cation is located on an inversion center and coordinated by two phenytoin anions and two ethylenediamine ligands in a distorted octahedral geometry. In the phenytoin anion, the two phenyl rings are twisted with respect to the central hydantoin ring, making dihedral angles of 77.49 (16) and 64.55 (15)°. Intramolecular and intermolecular N-HO hydrogen bonding is present in the crystal structure.
