چکیده
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.

The structure of the title compound, [Co(NO2)2(NH2CH2CH2NH2)2][Co(NO2)4(NH2CH2CH2NH2)]·H2O, was redetermined with a modern CCD-equipped diffractometer. In comparison with the original determination based on photographic data [Kushi et al. (1976 ▶). Inorg. Nucl. Chem. Lett. 12, 629-633], the current study allows the location of reliable postions for the H atoms and thus leads to better understan...

In the title compound, [Co(C(8)H(6)N(3))(2)(C(2)H(8)N(2))]NO(3)·H(2)O, the Co(III) ion is coordinated by four N atoms from two 2-(pyridin-2-yl)-1,3-imidazol-1-ide ligands and two N atoms of ethyl-enediamine in a distorted octa-hedral geometry. In the crystal, classical N-H⋯N(O) and O-H⋯N(O) hydrogen bonds connect all the isolated components together to yield a three-dimensional structure.
