Dibromidotetra­kis(1H-indazole-κN 2)copper(II)

The Cu atom in the title compound, [CuBr2(C7H6N2)4], is surrounded by four N-heterocycles that define an N4 square-planar geometry. The coordination geometry is distorted towards an elongated octa­hedron 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

Dichloridobis(4-methyl-3,5-diphenyl-1H-pyrazole-κN 2)copper(II)

The asymmetric unit of the title compound, [CuCl2(C16H14N2)2], comprises half of the complex. The CuII atom lies on a crystallographic twofold rotation axis and shows a significantly distorted tetra­hedral coordination geometry. The dihedral angle between the phenyl rings is 74.3 (2)°. The crystal structure is stabilized by inter­molecular π–π inter­actions [centroid–centroid distances = 3.635 (2)–3.803 (3) Å]

Bis(4-methyl-3,5-diphenyl-1H-pyrazole-κN 2)silver(I) nitrate

In the title complex, [Ag(C16H14N2)2]NO3, the geometry around the AgI ion is T-shaped with two short Ag—N bonds to the pyrazole ligand and one long Ag—O bond to the nitrate anion. The crystal structure is stabilized by inter­molecular N—H⋯O, C—H⋯O and C—H⋯π inter­actions

Chlorido(1H-imidazole-κN 3)bis­(triphenyl­phosphane-κP)copper(I)

In the title complex, [CuCl(C3H4N2)(C18H15P)2], the coordination geometry around CuI is distorted tetra­hedral formed by two triphenyl­phosphane ligands, an imidazole ligand and a chloride group. An intra­molecular C—H⋯Cl inter­action occurs. The crystal packing is stabilized by inter­molecular N—H⋯Cl hydrogen bonds, which form an extended chain parallel to [010]

Bis[bis­(3,5-dimethyl-1H-pyrazol-1-yl)­borato]cobalt(II)

The asymmetric unit of the title compound, [Co(C10H16BN4)2], comprises one unit of the complex. The geometry around the CoII ion is a distorted tetra­hedron. The dihedral angles between the pyrazole rings in the two ligands are 47.19 (15) and 47.20 (16)°, while that between the coordination planes is 79.77 (7)°

1-Phenyl-2-trifluoro­methyl-4-quinolone

In the title mol­ecule, C16H10F3NO, the N-bound phenyl ring is oriented nearly orthogonal to the quinolinyl ring in order to avoid steric clashes with the trifluoro­methyl substituent [dihedral angle 89.7 (1)°]

Bromidotetra­kis­(2-isopropyl-1H-imidazole-κN 3)copper(II) bromide

The CuII atom in the title salt, [CuBr(C6H10N2)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

(5-Hy­droxy-3-methyl-5-phenyl-4,5-dihydro-1H-pyrazol-1-yl)(pyridin-4-yl)methanone monohydrate

In the title compound, C16H15N3O2·H2O, the mean plane of the approximately planar pyrazole ring [maximum deviation = 0.0474 (18) Å] makes dihedral angles of 86.32 (11) and 45.04 (10)° with the phenyl and pyridine rings, respectively. The dihedral angle between the phenyl and pyridine rings is 69.62 (11)°. In the crystal, inter­molecular O—H⋯O and O—H⋯N hydrogen bonds connect the components into chains along [010]. The crystal structure is further stabilized by π–π stacking inter­actions with centroid–centroid distances of 3.7730 (12) Å

Bromidotetra­kis­(1H-2-ethyl-5-methyl­imidazole-κN 3)copper(II) bromide

The CuII ion in the title compound, [CuBr(C6H10N2)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 CuII and Br− atoms lie on a crystallographic fourfold axis. In the crystal, the [CuBr(C6H10N2)4]+ complex cations are linked to the uncoordinated Br− anions (site symmetry ) 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)
