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

ABSTRACT: 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].

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.

[(Pyridine-2,6-dicarboxyl-ato)copper(II)]-?-(pyridine-2,6-dicarboxyl-ato)-[bis-(ethyl-enediamine)-copper(II)]-?-(pyridine-2,6-dicarboxyl-ato)-[(pyridine-2,6-dicarboxyl-ato)copper(II)] ethyl-enediamine monosolvate tetra-hydrate.

Project description:The title compound, [Cu(3)(C(7)H(3)NO(4))(4)(C(2)H(8)N(2))(2)]·C(2)H(8)N(2)·4H(2)O, was obtained by the reaction of copper(II) acetate dihydrate with pyridine-2,6-dicarb-oxy-lic acid (H(2)dipic) and ethyl-enediamine (en) in an aqueous solution. All of the Cu(II) atoms in the trinuclear centrosymmetric title complex are six-coordinated in a distorted octa-hedral geometry with N(2)O(4) and N(4)O(2) environments for the outer and central Cu(II) atoms, respectively. Various inter-actions, including numerous O-H?O and C-H?O hydrogen bonds and C-O?? stacking of the pyridine and carboxyl-ate groups [O?centroid distances = 3.669?(2) and 3.668?(2)?Å] are observed in the crystal structure.

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-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-bis-(perchlorato)(1,10-phenanthroline)copper(II).

Project description:In the title compound, [Cu(ClO(4))(2)(C(12)H(8)N(2))(H(2)O)(2)], the Cu(II) atom is coordinated in a square-planar fashion by the two N atoms of a chelating 1,10-phenanthroline ligand and by two water mol-ecules trans to the N atoms. The coordination sphere of the metal atom is augmented by O atoms of two weakly bonded perchlorate anions, thus yielding a strongly distorted CuN(2)O(4) octa-hedral environment. The crystal packing is stabilized by O-H⋯O hydrogen bonds between the water mol-ecules and the perchlorate anions. In addition, the organic mol-ecules are associated by π-π stacking inter-actions between symmetry-equivalent anti-parallel non-nitro-gen aromatic rings, with inter-planar distances of 3.543 (2) Å.

Project description:In the title compound, [Cu(ClO(4))(2)(CH(3)CN)(2)(H(2)O)(2)], the Cu(2+) ion, located on a special position (site symmetry [Formula: see text]), is coordinated by six monodentate ligands, viz. an N-coordin-ated acetonitrile, a perchlorate anion and a water mol-ecule, and their symmetry-related counterparts. The perchlorate anion is disordered over two sets of sites with occupancies of 0.53?(2) and 0.47?(2). The crystal structure is stabilized by O-H?O hydrogen bonds involving the perchlorate ion and aqua H atoms.

Intra-molecular and inter-molecular N-H?O hydrogen bonding is present in the crystal structure.

Project description:In the title compound, [Cu(ClO(4))(2)(C(12)H(13)N(3))(C(2)H(3)N)], the Cu(II) atom is six-coordinate in a Jahn-Teller distorted octahedral geometry, with coordination by the tridentate chelating ligand, an acetonitrile mol-ecule, and two axial perchlorate anions. The tridentate ligand bis-(2-pyridylmeth-yl)amine chelates meridionally and equatorially while an acetonitrile mol-ecule is coordinated at the fourth equatorial site. The two perchlorate anions are disordered with site occupancy factors of 0.72/0.28. The amine H is involved in intra-molecular hydrogen bonding to the perchlorate O atoms and there are extensive but weak inter-molecular C-H?O inter-actions.
