Bromidotetra-kis-(2-ethyl-1H-imidazole-?N (3))copper(II) bromide.

ABSTRACT: The Cu(II) ion in the title mol-ecular salt, [CuBr(C5H8N2)4]Br, is coordinated in a square-pyramidal geometry by four N atoms of imidazole ligands and one bromide anion in the apical position. In the crystal, the ions are linked by N-H?Br hydrogen bonds involving both the coordinating and the free bromide species as acceptors. A C-H?Br inter-action is also observed. Overall, a three-dimensional network results.

Bromidotetra-kis-(1H-2-ethyl-5-methyl-imidazole-?N)copper(II) bromide.

Project description:The Cu(II) ion in the title compound, [CuBr(C(6)H(10)N(2))(4)]Br, is coordinated in a square-based-pyramidal geometry by the N atoms of four imidazole ligands and a bromide anion in the apical site. Both the Cu(II) and Br(-) atoms lie on a crystallographic fourfold axis. In the crystal, the [CuBr(C(6)H(10)N(2))(4)](+) complex cations are linked to the uncoordinated Br(-) anions (site symmetry [Formula: see text]) by N-H?Br hydrogen bonds, generating a three-dimensional network. The ethyl group of the imidazole ligand was modelled as disordered over two orientations with occupancies of 0.620?(8) and 0.380?(8).

Bromidotetra-kis-(2-isopropyl-1H-imidazole-?N)copper(II) bromide.

Project description:The Cu(II) atom in the title salt, [CuBr(C(6)H(10)N(2))(4)]Br, is coordinated in a square-pyramidal geometry by four imidazole N atoms and one bromide anion that is located at the apex of the pyramid. The cations and the anions form a two-dimensional network parallel to (001) through N-H?Br hydrogen bonds.

Tetra-kis(1-ethyl-1H-imidazole-?N)bis-(thio-cyanato-?N)cadmium(II).

Project description:The structure of the title compound, [Cd(NCS)(2)(C(5)H(8)N(2))(4)], consists of isolated mol-ecules of [Cd(NCS)(2)(Eim)(4)] (Eim = 1-ethyl-imidazole), which contain a compressed octa-hedral CdN(6) chromophore. The NCS(-) anions are trans and four N atoms from the 1-ethyl-imidazole ligands define the equatorial plane. The mean Cd-N(Eim) and Cd-N(NCS) distances are 2.334?(4) and 2.379?(5)?Å, respectively. Weak C-H?N inter-actions contribute to the crystal packing stability.

Hexa-kis-(1H-imidazole-?N)iron(II) sulfate-1H-imidazole (1/2).

Project description:The asymmetric unit of the title compound, [Fe(C(3)H(4)N(2))(6)]SO(4)·2C(3)H(4)N(2), contains two complex cations, two sulfate anions and four imidazole mol-ecules. In both cations, the Fe(II) atom is coordinated by six monodentate imidazole ligands and exhibits a slightly distorted octa-hedral coordination geometry. The Fe-N distances [2.184?(4)-2.218?(4)?Å] point to a high-spin state of the Fe(2+) ions. N-H?O hydrogen bonds between the ionic components generate a three-dimensional framework containing corrugated channels along [001], which are filled by N-H?N hydrogen-bonded imidazole chains.

trans-Bis(nitrato-?O)tetra-kis-(1-vinyl-1H-imidazole-?N(3))copper(II).

Project description:In the title compound, [Cu(NO(3))(2)(C(5)H(6)N(2))(4)], the Cu(II) ion is located on an inversion centre. It features a Jahn-Teller-distorted octa-hedral coordination geometry, defined by four N atoms of four 1-vinyl-imidazole ligands in the equatorial plane and two nitrate O atoms in the axial positions. The nitrate anion is disordered over two sets of sites in a 0.801?(6):0.199?(6) ratio. In the crystal, the complex mol-ecules are linked by weak inter-molecular C-H?O and C-H?? inter-actions.

Project description:In the title compound, [NiCl(2)(C(10)H(10)N(2))(4)], the Ni(II) ion is located on an inversion center being coordinated by four N atoms from two pairs of symmetry-related 1-benzyl-1H-imidazole ligands and two chloride anions in a distorted octa-hedral geometry. Weak inter-molecular C-H?Cl hydrogen bonds link the mol-ecules into layers parallel to the ab plane.

Dibromidotetra-kis(1H-indazole-?N)copper(II).

Project description:The Cu atom in the title compound, [CuBr(2)(C(7)H(6)N(2))(4)], is surrounded by four N-heterocycles that define an N(4) square-planar geometry. The coordination geometry is distorted towards an elongated octa-hedron owing to the presence of the two Br(-) anions, which are located at about 3?Å above and below the square plane. There are two independent molecules in the asymmetric unit, each with their Cu atom lying on an inversion centre.

Di-μ-nitrito-κO:O-bis-[bis-(1-ethyl-1H-imidazole-κN)(nitrito-κO)copper(II)].

Project description:In the structure of the title compound, [Cu(2)(NO(2))(4)(C(5)H(8)N(2))(4)], the asymmetric unit consists of two moieties containing one Cu ion, two nitrite ions and two 1-ethyl-1H-imidazole mol-ecules associated via weak Cu-O inter-actions. Each Cu(II) atom displays an elongted square-pyramidal CuN(2)O(3) coordination geometry with a slight tetra-hedral distortion in the basal plane. The dimeric units are linked into a three-dimensional network by C-H⋯O hydrogen bonds.

Project description:The title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)](n), is composed of one-dimensional linear chains running parallel to the a axis. In the chain, trans-[Cu(imidazole)(2)](2+) units are sequentially bridged by bis-bidentate oxalate ligands, resulting in an octa-hedral CuO(4)N(2) donor set. The Cu⋯Cu separation through the oxalate bridge is 5.620 (5) Å. Both the Cu atoms and the C-C bond of the oxalate bridge are bis-ected by inversion centres.
