title: Bis(2,4-dioxo-5,5-diphenyl-imidazol-idin-ido-κN)bis-(propane-1,3-diamine-κN,N')cobalt(II).
abstract: The complex mol-ecule of the title compound, [Co(C(15)H(11)N(2)O(2))(2)(C(3)H(10)N(2))(2)], has crystallographically imposed inversion symmetry. The Co(II) atom displays a distorted octa-hedral coordination geometry. In the phenytoin anion, the two phenyl rings form dihedral angles of 62.26 (8) and 57.47 (9)° with the central imidazole ring. Intra-molecular N-H⋯O and C-H⋯O hydrogen bonds occur. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds forming a three-dimensional network.
