Bis(ethyl-enediamine-?N,N')bis-(phenytoinato-?N)cobalt(II).

ABSTRACT: THE TITLE COMPOUND [SYSTEMATIC NAME: bis(2,5-dioxo-4,4-diphenylimidazolidin-1-ido-?N(1))bis(ethylenediamine-?(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.

Tris(ethyl-enediamine)cobalt(II) sulfate.

Project description:The structure of the title compound, [Co(II)(C(2)H(8)N(2))(3)]SO(4), the cobalt example of [M(C(2)H(8)N(2))(3)]SO(4), is reported. The Co and S atoms are located at the 2d and 2c Wyckoff sites (point symmetry 32), respectively. The Co atom is coordinated by six N atoms of three chelating ethyl-enediamine mol-ecules generated from half of the ethyl-enediamine mol-ecule in the asymmetric unit. The O atoms of the sulfate anion are disordered mostly over two crystallographic sites. The third disorder site of O (site symmetry 3) has a site occupancy approaching zero. The H atoms of the ethyl-enediamine mol-ecules inter-act with the sulfate anions via inter-molecular N-H?O hydrogen-bonding inter-actions.

In the crystal, the complex cations are connected by N-H⋯O hydrogen bonds between ethyl-endiamine NH groups and O atoms from the perchlorate anions and peroxide O atoms.

Project description:In the title compound, [Cu(SO(4))(C(2)H(8)N(2))(2)](n), the Cu, S and two O atoms lie on a mirror plane.

Project description:The Co ion in the title salt, [Co(NO(3))(H(2)NCH(2)CH(2)NH(2))(2)](OH)(NO(3)), has oxidation state + III and is coordinated by four N atoms from two ethyl-enediamine mol-ecules and two O atoms from a nitrate anion in a distorted octa-hedral geometry. The charge of the complex cation is balanced by a hydroxide anion and a nitrate anion.

There are two independent ion pairs with similar configurations in the unit cell. Both uncoordinated nitrate counter-anions are disordered.

Project description:In the title complex, [Cu(C(2)H(8)N(2))(2)(H(2)O)(2)](C(13)H(9)O(2))(2)·2.66H(2)O, the Cu(II) centre (located at an inversion centre) is coordinated by two bidentate ethyl-enediamine (en) ligands and two water O atoms in a typical Jahn-Teller distorted octahedral geometry.

In the crystal, the cations and anions are disposed in alternating layers. One of the water mol-ecules of crystallization is disordered and the other has a fractional occupation. In the 2/3 occupancy component, water mol-ecules are organized into a chain composed of hexa-meric units inter-connected by carboxyl-ate bridges.

One of the uncoordinated water molecules has a site occupation factor of 0.5.
