title: Bis(ethyl-enediamine-κN,N')bis-(phenytoinato-κN)cobalt(II).
abstract: THE TITLE COMPOUND [SYSTEMATIC NAME: bis(2,5-dioxo-4,4-diphenylimidazolidin-1-ido-κN(1))bis(ethylenediamine-κ(2)N,N')cobalt(II)], [Co(C(15)H(11)N(2)O(2))(2)(C(2)H(8)N(2))(2)], has site symmetry . The Co(II) cation is located on an inversion center and coordinated by two phenytoin anions and two ethyl-enediamine ligands in a distorted octa-hedral 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)°. Intra-molecular and inter-molecular N-H⋯O hydrogen bonding is present in the crystal structure.
