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

ABSTRACT: 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.

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.

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].

Bis(acetato-κO,O')bis-[4-(dimethyl-amino)-pyridine-κN]copper(II).

Project description:In the mononuclear title complex, [Cu(CH(3)COO)(2)(C(7)H(10)N(2))(2)], the Cu(II) ion, located on a crystallographic inversion centre, is six coordinated by two N atoms of two 4-(dimethyl-amino)-pyridine (DMAP) ligands in apical positions and four O atoms from two symmetry-related opposite acetate anions, which are asymmetrically bonded in the equatorial plane. The complex and the crystal packing of the complex are stabilized by intra- and inter-molecular C-H⋯O hydrogen bonds, giving R(4) (2)(10) rings and generating a layer-like structure.

Extensive inter-molecular O-H?O and N-H?O hydrogen bonding is present in the crystal structure.
