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

ABSTRACT: 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-bis(ethyl-enediamine-κN,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-(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.

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. The Cu atom is in a distorted octa-hedral environment and the ethyl-enediamine ligand is in a gauche conformation. The sulfate dianion is bridging, forming a one-dimensional chain. A two-dimensional net parallel to (001) is generated by N-H?O hydrogen bonding between the chains.

(Ethyl-enediamine-?(2)N,N')bis-(perchlorato-?O)bis-(pyridine-?N)copper(II).

Project description:In the title compound, [Cu(ClO(4))(2)(C(2)H(8)N(2))(C(5)H(5)N)(2)], the Cu(II) cation is located on a twofold rotation axis and is coordinated by four N and two O atoms in a tetragonally distorted octahedral geometry. The crystal packing can be described as ClO(4) tetra-hedra and CuN(4)O(2) octa-hedra alternating in a zigzag fashion along the c axis. 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].

trans-Diaqua-bis(ethyl-enediamine-?N,N')copper(II) bis[3-(3-pyrid-yl)propionate] dihydrate.

Project description:The asymmetric unit of the title complex, [Cu(C(2)H(8)N(2))(2)(H(2)O)(2)](C(8)H(8)NO(2))(2)·2H(2)O, contains one anion, one half-cation and one water mol-ecule. The Cu(II) atom in the [Cu(en)(2)(H(2)O)(2)](2+) cation (en is ethyl-enediamine) lies on an inversion centre. The four N atoms of the en ligands in the equatorial plane around the Cu(II) atom form a slightly distorted square-planar arrangement, while the slightly distorted Jahn-Teller octa-hedral coordination is completed by two water O atoms in axial positions. In the crystal structure, intra- and inter-molecular N-H?O and O-H?O hydrogen bonds form a three-dimensional network.

Project description:The central CuN(2)O(4) motif of the title compound, [Cu(ClO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a Jahn-Teller-distorted octa-hedral geometry around the metal atom, showing a considerably long Cu-O bond distance of 2.5058 (12) Å towards the second perchlorate group, giving a (4 + 1+1)-type coordination mode. In the crystal, the components are linked via inter-molecular O-H⋯O hydrogen bonds, forming layers parallel to (001). Additional stabilization within these layers is provided by π-π [centroid-centroid distances of 3.7848 (9)-4.4231 (9) Å] stacking inter-actions.

Intra-molecular O-H?O hydrogen bonds link the water mol-ecules to the carboxyl-ate groups. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 4.6?(3) and 3.7?(2)°, while the pyridine rings and the benzene rings are oriented at dihedral angles of 6.82?(11) and 3.63?(14)°. In the crystal, inter-molecular O-H?O hydrogen bonds link the mol-ecules into chains propagating along [010]. C-H?O inter-actions and a ?-? contact between the pyridine rings [centroid-centroid distance = 3.469?(2)?Å] are also observed.
