Bis(ethylenediamine-κ2N,N′)bis(phenytoinato-κN)cobalt(II)

Abstract

The title compound [systematic name: bis(2,5-dioxo-4,4-diphenylimidazolidin-1-ido-κN1)bis(ethylenediamine-κ2N,N′)cobalt(II)], [Co(C15H11N2O2)2(C2H8N2)2], has site symmetry overline{1}. The CoII 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—H...O hydrogen bonding is present in the crystal structure.
