Tetra-?-acetato-?O:O'-bis-[(3,5-di-methyl-1H-pyrazole-?N)-copper(II)].

ABSTRACT: The dinuclear centrosymmetric title compound, [Cu(2)(CH(3)CO(2))(4)(C(5)H(8)N(2))(2)], has a distorted square-pyramidal coordination geometry around each Cu(II) atom in which four O atoms from the bridging acetate ligands form the basal plane while two N atoms from the pyrazole ligands occupy the apical positions. The crystal has two half mol-ecules in the asymmetric unit with a Cu?Cu distance of 2.6762?(4)?Å. Disorder was found for two O atoms and two C atoms of one acetate ligand and refined with occupancies of 0.265?(7) and 0.735?(7). The crystal also features mol-ecules linked through two N-H?O hydrogen bonds resulting in one-dimensional chains extending along the crystallographic b axis.

Bis(acetato-κO,O')bis-(3,5-dimethyl-1H-pyrazole-κN)copper(II).

Project description:In the title compound, [Cu(C(2)H(3)O(2))(2)(C(5)H(8)N(2))(2)], the Cu(II) atom has a distorted tetra-gonal-bipyramidal geometry, with the equatorial plane formed by two N atoms belonging to two 3,5-dimethyl-1H-pyrazole ligands and two O atoms from two acetate anions. The second O atoms of the acetate groups provide elongated Cu-O axial contacts, so that the acetates appear to be coordinated in a pseudo-chelate fashion. The pyrazole ligands are situated in cis positions with respect to each other. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming a one-dimensional chain.

Chloridotris(3,5-dimethyl-1H-pyrazole-?N)(formato-?O)copper(II)-dichlorido-bis(3,5-dimethyl-1H-pyrazole-?N)copper(II) (2/1).

Project description:The asymmetric unit of the title compound, [Cu(CHO(2))Cl(C(5)H(8)N(2))(3)](2)·[CuCl(2)(C(5)H(8)N(2))(2)] or 2[A]·[B], contains one A mol-ecule and one half-molecule of B, located on a centre of inversion. The Cu(II) environments in A and B are different. In A, the Cu(II) atom is coordinated by three N atoms from three 3,5-dimethyl-1H-pyrazole (L) ligands, one O atom from a formate ligand and a chloride anion in an axial position [Cu-Cl = 2.4275?(7)?Å] in a distorted tetra-gonal-pyramidal geometry. The Cu(II) atom in B is coordinated by two N atoms from two L ligands and two chloride anions [Cu-Cl = 2.2524?(6)?Å] in a distorted square-planar geometry. In the crystal, inter-molecular N-H?O hydrogen bonds link mol-ecules A into centrosymmetric dimers. Inter-molecular N-H?Cl hydrogen bonds further link these dimers with the B mol-ecules, forming chains propagating in [101].

Octa-aqua-bis(μ(2)-1H-pyrazole-3,5-di-carboxyl-ato)tricopper(II) tetra-hydrate.

Project description:In the trinucler Cu(II) complex mol-ecule of the title compound, [Cu(3)(C(5)HN(2)O(4))(2)(H(2)O)(8)]·4H(2)O, the central Cu(II) atom is located on an inversion centre and is coordinated in a distorted octa-hedral geometry. The equatorial sites are occupied by two N and two O atoms from two pyrazole-3,5-dicarboxyl-ate ligands and the axial positions are occupied by two water mol-ecules. The two other symmetry-related Cu(II) atoms are penta-coordinated and assume a square-pyramidal geometry. In the crystal structure, coordinated and uncoordinated water mol-ecules and carboxyl-ate O atoms are linked by O-H⋯O hydrogen bonds.

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

Project description:The asymmetric unit of the title compound, [CuCl(2)(C(16)H(14)N(2))(2)], comprises half of the complex. The Cu(II) atom lies on a crystallographic twofold rotation axis and shows a significantly distorted tetra-hedral coordination geometry. The dihedral angle between the phenyl rings is 74.3 (2)°. The crystal structure is stabilized by inter-molecular π-π inter-actions [centroid-centroid distances = 3.635 (2)-3.803 (3) Å].

Aqua-bis(3,5-dimethyl-1H-pyrazole-κN)(oxalato-κO,O')copper(II).

Project description:In the title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)(H(2)O)], the Cu(II) atom is coordinated in a slightly distorted square-pyramidal geometry by two N atoms belonging to the two 3,5-dimethyl-1H-pyrazole ligands, two O atoms of the oxalate anion providing an O,O'-chelating coordination mode, and an O atom of the water mol-ecule occupying the apical position. The crystal packing shows a well defined layer structure. Intra-layer connections are realised through a system of hydrogen bonds while the nature of the inter-layer inter-actions is completely hydro-phobic, including no hydrogen-bonding inter-actions.

Tetra-aqua-bis(1,10-phenanthroline)bis-[?(2)-1H-pyrazole-3,5-dicarboxyl-ato(3-)]tricopper(II) dihydrate.

Project description:The title compound, [Cu(3)(C(5)HN(2)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, is a trinuclear copper(II) complex in which two centrosymmetrically related pyrazole-3,5-dicarboxyl-ate(3-) and 1,10-phenanthroline ligands bind three Cu(II) atoms, with one Cu(II) atom located on a center of symmetry. In each complex, there are four coordinated water mol-ecules and two solvent water mol-ecules, which participate in extensive hydrogen-bond patterns. These inter-actions, as well as ?-? inter-actions between neighbouring 1,10-phenanthroline ligands [shortest atom-to-atom distance = 3.363?(3)?Å], extend the crystal structure into a three-dimensional supra-molecular network.

Tetra-imidazole-bis(trichloro-acetato)copper(II).

Project description:The title compound, [Cu(C(2)Cl(3)O(2))(2)(C(3)H(4)N(2))(4)], was prepared by the reaction of imidazole and trichloro-acetatocopper(II). The Cu(II) atom adopts a distorted octa-hedral coordination geometry, binding the N atoms of four imidazole ligands and the carboxyl-ate O atoms of two trichloro-acetate anions. The mol-ecular structure and packing are stabilized by N-H?O hydrogen-bonding inter-actions. Close inter-molecular Cl?Cl contacts [3.498?(3)?Å] are also found in the structure.

Aqua-bis-(3,5-dimethyl-1H-pyrazole-?N)(oxydiacetato-?O,O',O'')copper(II) dihydrate.

Project description:In the title compound, [Cu(C(4)H(4)O(5))(C(5)H(8)N(2))(2)(H(2)O)]·2H(2)O, the Cu(II) cation assumes a distorted octa-hedral coordination geometry formed by two 3,5-dimethyl-1H-pyrazole ligands, one oxydiacetate (ODA) dianion and one coordinated water mol-ecule. The tridentate ODA ligand chelates to the Cu cation in a facial configuration with a longer Cu-O bond [2.597?(3)?Å], and both chelating rings display envelope conformations. In the mol-ecule, the two pyrazole rings are twisted with respect to each other at a dihedral angle of 57.5?(3)°. Extensive inter-molecular O-H?O and N-H?O hydrogen bonding is present in the crystal structure.
