Di-?-bromido-bis-[bromido(di-2-pyridylmethane-diol-?N,N')copper(II)] dihydrate.

ABSTRACT: The centrosymmetric title complex, [Cu(2)Br(4)(C(11)H(10)N(2)O(2))(2)]·2H(2)O, was one of three complexes isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 1:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand di-2-pyridylmethane-diol. The copper centers are bridged by bromide donors, leading to a Cu-Cu distance of 4.090?(6)?Å. The crystals form as non-merohedral twins with two components related by a 180° rotation around the normal to [100]; the selected sample had a twin ratio of 0.63:0.37.

Bis(di-2-pyridylmethane-diol-?N,O,N')copper(II) bis-(tetra-fluorido-borate) dihydrate.

Project description:The title complex, [Cu(C(11)H(10)N(2)O(2))(2)](BF(4))(2)·2H(2)O, was isolated as a dihydrate from a 1:2 molar mixture of copper(II) tetra-fluoridoborate hexa-hydrate with di-2-pyridyl ketone in aqueous solution. The centrosymmetric complex cation is structurally similar to that found in previously reported salts and exhibits Cu-O bonds deviating by 25 degrees from an octa-hedral geometry by the so-called 'off-axis angle' distortion. The BF(4) (-) anion exhibits a two site disorder of the fluorine atoms [ratio 0.210?(8):0.790?(8)].

Bis[(2-quinol-yl)methane-diol-κN,O](sulfato-κO)copper(II) dihydrate.

Project description:In the title compound, [Cu(SO(4))(C(10)H(9)NO(2))(2)]·2H(2)O, the Cu(II) ion is chelated by two (2-quinol-yl)methane-diol ligands and coordinated by a monodentate sulfate ligand in a distorted trigonal-bipyramidal environment, with O atoms occupying the equatorial sites and N atoms in the axial sites. The dihedral angle between the two essentially planar quinoline ring systems is 45.02 (9)°. In the crystal structure, an extensive O-H⋯O hydrogen-bonding network forms layers parallel to the ab plane.

Poly[bis(phenethyl-ammonium) [di-bromido-plumbate(II)]-di-μ-bromido]].

Project description:Crystals of the title compound, {(C(6)H(5)C(2)H(4)NH(3))(2)[PbBr(4)]}(n), were grown at room temperature from a solution in N,N-dimethyl-formamide (DMF) using nitro-methane as the poor solvent. This perovskite-type organic-inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr(6) octa-hedra separated by bilayers of phenethyl-ammonium cations. The octa-hedra are rotated and tilted due to N-H⋯Br hydrogen bonds with the ammonium groups, generating a superstructure in the unit cell similar to that of the tetra-chloridoplumbate (C(6)H(5)C(2)H(4)NH(3))(2)[PbCl(4)].

Di-μ-bromido-bis-({bis-[2-(2-pyrid-yl)eth-yl]amine}copper(II)) bis-(perchlorate).

Project description:Each Cu atom in the dinuclear centrosymmetric title complex, [Cu(2)Br(2)(C(14)H(17)N(3))(2)](ClO(4))(2), is ligated in a distorted square-pyramidal geometry (τ = 0.31) by a tridentate bis-[2-(2-pyrid-yl)eth-yl]amine ligand, and by two bridging Br atoms. In addition, the dinuclear species is stabilized by two hydrogen-bonded perchlorate anions.

Bis(di-2-pyridylmethane-diol-κN,O,N')copper(II) dl-tartrate.

Project description:The reaction of di-2-pyridyl ketone with copper dichloride dihydrate and tartaric acid in water afforded the title compound, [Cu(C(11)H(10)N(2)O(2))(2)]C(4)H(4)O(6). The Cu(II) atom lies on an inversion center N,O,N'-chelated by two di-2-pyridylmethane-diol ligands in a tetragonally distorted octa-hedral geometry. The tartrate anion is also located on an inversion center and has disordered hydroxyl groups, each with an occupancy factor of 0.5. The hydroxyl groups of the complex cation are hydrogen bonded to the carboxyl-ate groups of the anion, thus connecting the two building units.

Di-?-methacrylato-?O:O'-bis-[aqua-bis(1,10-phenanthroline-?N,N')copper(II)] dinitrate dihydrate.

Project description:The title complex, [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](NO(3))(2)·2H(2)O, contains a dimeric [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) dication with two five-coordinated Cu(II) ions linked by two methacrylate ions in a syn-syn bridging arrangement. The dication possesses pseudo-twofold rotational symmetry. The penta-coordination of each Cu(II) ion has a distorted square-pyramidal geometry, with two N donors from a phenanthroline ligand and two carboxyl-ate O atoms occupying basal sites and the apical position being occupied by a water mol-ecule. In the crystal packing, mol-ecules are linked to form a three-dimensional framework by O-H?O and C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distances of 3.6039?(15), 3.5301?(15), 3.6015?(15), 3.6496?(15) and 3.6858?(15)?Å].

Di-?-bromido-bis-[bromido(4,4'-dimethyl-2,2'-bipyridine-?N,N')mercury(II)].

Project description:The asymmetric unit of the title compound, [Hg(2)Br(4)(C(12)H(12)N(2))(2)], contains one half-mol-ecule. The Hg(II) atom is five-coordinated in a trigonal-bipyramidal configuration by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine ligand, two bridging Br and one terminal Br atom, leading to a centrosymmetric dimeric mol-ecule. There is a ?-? contact between the pyridine rings [centroid-to-centroid distance = 3.756?(5)?Å].

Bis(1-methyl-piperazine-1,4-diium) di-?-bromido-bis-[tetra-bromido-bismuthate(III)] dihydrate.

Project description:In the title hydrated salt, (C5H14N2)2[Bi2Br10]·2H2O, the com-plete [Bi2Br10](4-) biocta-hedron is generated by crystallographic inversion symmetry. The diprotonated piperazine ring adopts a chair conformation, with the methyl group occupying an equatorial position. In the crystal, the tetra-anions and water mol-ecules are linked by O-H?Br and O-H?(Br,Br) hydrogen bonds to generate [100] chains. The chains are crosslinked by N-H?Br, N-H?O and C-H?Br hydrogen bonds originating from the piperazinediium dications, thereby forming a three-dimensional network.

Bis[2,6-bis-(2-meth-oxy-phen-yl)pyridinium] di-μ-bromido-bis-[dibromidocuprate(II)].

Project description:The title salt, (C(19)H(18)NO(2))(2)[Cu(2)Br(6)], was obtained from an attempt to synthesize the copper(II) complex of 2,6-bis-(2-meth-oxy-phen-yl)pyridine (L) from a reaction between CuBr(2) and one equivalent of L in CH(2)Cl(2) at room temperature. The resulting compound is the salt of the 2,6-bis-(2-meth-oxy-phen-yl)pyridinium cation and 0.5 equivalents of a hexa-bromido-dicuprate(II) dianion. Both meth-oxy groups of the cationic pyridinium moiety are directed towards the N atom of the pyridine ring as a result of intra-molecular N-H⋯O hydrogen bonds. The centrosymmetric hexabromidodicuprate dianion possesses a distorted tetra-hedral geometry at the copper ion. The Cu-Br bond lengths are 2.3385 (7) and 2.3304 (7) Å for the terminal bromides, whereas the bond length between the Cu atom and two bridging bromides is slightly longer [2.4451 (6) Å].
