ABSTRACT: In the title compound, [Zn(C(15)H(11)N(2)O(2))(2)(C(2)H(8)N(2))], the Zn(II) atom is coordinated in a distorted tetra-hedral geometry. Intra-molecular N-H?O, C-H?O and C-H?N hydrogen bonds occur. In the crystal, mol-ecules are linked by inter-molecular N-H?O hydrogen bonds, forming a three-dimensional network.

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

Project description: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.

The structure is stabilized by intermolecular N-H?O and C-H?O hydrogen bonds, as well as ?-? interactions [centroid-centroid distance = 3.7179?(15)?Å].

Diaqua-bis(ethyl-enediamine-?N,N')copper(II) bis-(4-phenyl-benzoate) 2.66-hydrate.

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. The amino groups and the water mol-ecules are disordered over two distinct crystallographic positions with occupancies of 1/3 and 2/3. 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.

Diaqua-bis(ethyl-enediamine-?N,N')copper(II) 2,2'-dithio-dinicotinate sesquihydrate.

Project description:In the title compound, [Cu(C(2)H(8)N(2))(2)](C(12)H(6)N(2)O(4)S(2))·1.5H(2)O, there are two half-molecules of the cationic complex in the asymmetric unit. The Cu(2+) ions lie on inversion centres and are octa-hedrally coordinated by two ethyl-enediamine (en) and two aqua ligands in a typical Jahn-Teller distorted environment with the water O atoms in the axial positions. Two 2-mercaptonicotinate units (mnic) are linked by a disulfide bridge. All the ethyl-enediamine N-H and O-H groups form inter-molecular hydrogen bonds with acceptor O and N atoms, giving rise to a three-dimensional network. One of the uncoordinated water molecules has a site occupation factor of 0.5.

Diaqua-(2,2'-bipyridine-5,5'-dicarboxyl-ato-?N,N')(ethyl-enediamine-?N,N')copper(II) 2.5-hydrate.

Project description:In the mol-ecule of the title compound, [Cu(C(12)H(6)N(2)O(4))(C(2)H(8)N(2))(H(2)O)(2)]·2.5H(2)O, the Cu(II) atom is six-coordinated in a distorted octa-hedral configuration by two N atoms from a 2,2'-bipyridine-5,5'-dicarboxyl-ate anion, two N atoms from ethyl-enediamine and two O atoms from two water mol-ecules. There are also two and a half water mol-ecules in the asymmetric unit. The planar five-membered ring is nearly coplanar with the adjacent pyridine rings, while the other five-membered ring adopts a twisted conformation, probably due to hydrogen bonding. In the crystal structure, intra- and inter-molecular N-H?O and O-H?O hydrogen bonds link the mol-ecules.

[N-(2-Hydroxy-ethyl)ethyl-enediamine]oxalatocopper(II).

Project description:In the title mononuclear copper(II) compound, [Cu(C(2)O(4))(C(4)H(12)N(2)O)], the Cu(II) ion has a slightly distorted square-pyramidal geometry, with a tridentate N-(2-hydroxy-ethyl)ethyl-enediamine (HydEt-en) and a bidentate oxalate (ox) ligand.

The complex mol-ecules participate in a supra-molecular assembly through N-H⋯O and O-H⋯O hydrogen bonds between HydEt-en and ox ligands.
