Bis(acetonitrile-?N)diaqua-bis-(perchlorato-?O)copper(II).

ABSTRACT: 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.

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.

(Acetonitrile)[bis-(2-pyridylmeth-yl)amine]bis-(perchlorato)copper(II).

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.

Diaqua-(2,2'-bipyridine-?N,N')bis-(perchlorato-?O)copper(II).

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 ?-? [centroid-centroid distances of 3.7848?(9)-4.4231?(9)?Å] stacking inter-actions.

Project description:In the title compound, [Cu(ClO(4))(C(2)H(3)N)(C(15)H(19)N(3)O)]ClO(4), the Cu(II) ion is coordinated by three N atoms and a hydroxyl-O atom of the tetra-dentate ligand, an O atom of a perchlorate ion and an N atom of an acetonitrile ligand giving a tetra-gonally distorted octa-hedral environment around the copper(II) atom. There is an offset inter-complex face-to-face π-π inter-action [centroid-centroid distance = 3.718 (2) Å] involving one of the pyridine rings of the ligand as well as an intra-complex O-H⋯O hydrogen-bonding inter-action between the coordinated hydroxyl group of the ligand and the perchlorate counter-ion.

Project description:In the title mononuclear complex, [Cu(C(9)H(9)O(3))(2)(H(2)O)(2)], the Cu(II) ion, located on an inversion center, is hexa-coordinated by four O atoms from two benzyl-oxyacetate ligands [Cu-O = 1.9420 (14) and 2.2922 (14) Å] and two water mol-ecules [Cu-O = 2.0157 (15) Å] in a distorted octa-hedral geometry.

Project description:In the title compound, [Cu(ClO(4))(2)(C(16)H(16)N(4)O)(2)]·2CH(3)CN, the Cu(II) atom, located on an inversion center, is in a tetra-gonally distorted octa-hedral environment, coordinated by four N atoms of two bidentate 3-ethyl-4-(4-methoxy-phen-yl)-5-(2-pyrid-yl)-4H-1,2,4-triazole ligands in equatorial positions and by the O atoms of two perchlorate groups in axial positions. The long axial Cu-O bond of 2.4743 (17) Å is the result of the Jahn-Teller effect.

Project description:In the title compound, [Cu(CH(3)CN)(C(14)H(12)N(2))(2)](BF(4))(2)·2CH(3)CN, the Cu(II) atom shows a distorted CuN(5) square-pyramidal geometry with the acetonitrile N atom in an equatorial site, which differs substanti-ally from the distorted trigonal-bipyramidal arrangement usually observed for five-coordinate complexes of Cu(II) with two phenanthroline-type ligands and one other ligand. The B atom of one of the BF(4) (-) anions is disordered over two sites in a 0.825 (2):0.175 (2) ratio. In the crystal, C-H⋯F hydrogen bonds help to establish the packing.

Di-?-perchlorato-bis-{?-2-[(2-pyrid-yl)methyl-amino-meth-yl]phenolato)dicopper(II) acetonitrile disolvate.

Project description:In the crystal of the dinuclear title compound, [Cu(2)(C(13)H(13)N(2)O)(2)(ClO(4))(2)]·2CH(3)CN, the two bridging perchlorate ions chelate to the two Cu(II) atoms in a ?-O:O' fashion on opposite sides of the equatorial plane. The Cu(II) ions display a distorted octa-hedral coordination geometry (in the usual 4 + 2 Jahn-Teller arrangement), each being coordinated by two O atoms from the two perchlorate ligands, and two N and O atoms from the reduced Schiff base ligand. The asymmetric unit contains two acetonitrile solvent mol-ecules. In the crystal structure, in addition to N-H?O hydrogen bonds, there are weak C-H?O inter-actions between the perchlorate O atoms and the reduced Schiff base ligand. C-H?N inter-actions are also present.
