Bis[dichlorido(5,5'-dimethyl-2,2'-bi-pyridine-?N,N')gold(III)] tetra-chlorido-aurate(III) dichloridooaurate(I).

ABSTRACT: The title compound, [Au(III)Cl(2)(C(12)H(12)N(2))](2)[Au(III)Cl(4)][Au(I)Cl(2)], contains three distinct types of Au atom. In the cation, the Au(III) atom is four-coordinated in a distorted square-planar arrangement by an N,N'-bidentate 5,5'-dimethyl-2,2'-bipyridine ligand and two terminal Cl atoms. In the [AuCl(4)](-) anion, the centrosymmetric Au(III) atom has a square-planar coordination. The centrosymmetric [AuCl(2)](-) anion is linear. Intra- and inter-molecular C-H?Cl hydrogen bonds help to establish the conformation and packing.

Dichlorido(4,4'-di-tert-butyl-2,2'-bi-pyridine-?N,N')gold(III) tetrachlorido-aurate(III) acetonitrile solvate.

Project description:In the title compound, [AuCl(2)(C(9)H(12)N)(2)][AuCl(4)]·C(2)H(3)N, there is a mirror plane passing through Au and the central C-C bond of the bipyridyl ligand in the cation, and through Au and two Cl atoms of the anion. A cis-AuCl(2)N(2) square-planar geometry for the cation and a square-planar AuCl(4) geometry for the anion result. The two C atoms and the N atom of the acetonitrile mol-ecule all have m site symmetries. In the crystal structure, weak C-H?Cl inter-actions may help to establish the packing.

Project description:In the crystal structure of the title salt, (C10H10N2)[ZnCl4], the bi-pyridine-diium dication is not planar, with a dihedral angle of 37.21 (9)° between the planes of the two pyridine rings. In the crystal, the slightly distorted [ZnCl4](2-) anions are packed into rods parallel to [001], with the organic cations arranged in corrugated layers parallel to (100). Cations and anions are linked through N-H⋯Cl hydrogen bonds, forming chains parallel to [20-1]. Additional C-H⋯Cl inter-actions consolidate the crystal packing.

Crystal structure of metronidazolium tetra-chlorido-aurate(III).

Project description:Metronidazole (MET) [systematic names: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazole and 2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethanol] is a medication that is used to treat infections from a variety of anaerobic organisms. As with other imidazole derivatives, metronidazole is also susceptible to protonation. However, there are few reports of the structures of metronidazolium derivatives. In the title compound, (C6H10N3O3)[AuCl4] [systematic name: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazol-3-ium tetra-chlorido-aur-ate(III)], the asymmetric unit consists of a metronidazolium cation, [H(MET)](+), and a tetra-chlorido-aurate(III) anion, [AuCl4](-), in which the Au(III) ion is in a slightly distorted square-planar coordination environment. In the cation, the nitro group is essentially coplanar with the imidazole ring, as indicated by an O N-C=C torsion angle of -0.2 (4)°, while the hy-droxy-ethyl group is in a coiled conformation, with an O(H)-C-C-N torsion angle of 62.3 (3)°. In the crystal, the anion and cation are linked by an inter-molecular O-H⋯Cl hydrogen bond. In addition, the N-H group of the metronidazolium ion serves as a hydrogen-bond donor to the O atom of the hy-droxy-ethyl group of a symmetry-related mol-ecule, leading to the formation of chains along [010].

Project description:In the title coordination polymer, [CdI(2)(C(12)H(12)N(2))](n), the Cd(2+) ion lies on a twofold rotation axis: it is six-coordinated in a distorted cis-CdN(2)I(4) octa-hedral geometry by two N atoms from a chelating 5,5'-dimethyl-2,2'-bipyridine ligands and four bridging iodide anions. The bridging function of the iodide ions leads to a chain structure propagating in [001].

1,3-Benzothia-zolium tetra-chlorido-aurate(III) tetra-hydro-furan solvate.

Project description:In the crystal structure of the title ionic compound (C(7)H(6)NS)[AuCl(4)]·C(4)H(8)O, the [AuCl(4)](-) anion shows a typical square-planar geometry. Numerous weak C-H?Cl hydrogen bonds between [AuCl(4)](-) and the 1,3-benzothia-zolium units form layers comprised of 24-membered rings in which hydrogen-bonded tetra-hydro-furan (THF) solvent mol-ecules are accommodated. C-H?Cl inter-actions between THF and [AuCl(4)](-) from adjacent layers result in bilayers. These are further stabilized by ?-? inter-actions between the thia-zole and benzene rings [centroid-centroid distance = 3.971?(3)?Å], resulting in the formation of a three-dimensional supra-molecular assembly.

Crystal structure of catena-poly[[chlorido-(4,4'-dimethyl-2,2'-bi-pyridine-?(2) N,N')copper(II)]-?-chlorido].

Project description:The title compound, [CuCl2(C12H12N2)] n , was obtained via a DMSO-mediated dehydration of Cu(4,4'-dimethyl-2,2'-bi-pyridine)-copper(II)·0.25H2O. The central Cu(II) atom is coordinated in a distorted trigonal-bipyramidal geometry by two N atoms of a chelating 4,4'-dimethyl-2,2'-bi-pyridine ligand [average Cu-N = 2.03?(3)?Å] and three Cl atoms, one terminal with a short Cu-Cl bond of 2.2506?(10)?Å, and two symmetry-equivalent and bridging bonds. The bridging Cl atom links the Cu(II) ions into chains parallel to [001] via one medium and one long Cu-Cl bond [2.3320?(10) and 2.5623?(9)?Å]. The structure displays both inter- and intra-molecular C-H?Cl hydrogen bonding.
