Dibromidobis(3,5-dimethyl-1H-pyrazole-κN)cobalt(II).

ABSTRACT: In the mononuclear title complex, [CoBr(2)(C(5)H(8)N(2))(2)], the Co(II) atom is coordinated by two N atoms from two monodentate 3,5-dimethyl-pyrazole ligands and two Br atoms in a highly distorted tetra-hedral geometry. In the crystal, the complex mol-ecules are linked by inter-molecular N-H⋯Br hydrogen bonds into chains along [101]. An intra-molecular N-H⋯Br hydrogen bond is also present.

Tris(3,5-dimethyl-1H-pyrazole-κN)(pyridine-2,6-dicarboxyl-ato-κO,N,O)cobalt(II) monohydrate.

Project description:The reaction of Co(NO(3))(2)·3H(2)O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C(7)H(3)NO(4))(C(5)H(8)N(2))(3)]·H(2)O. The Co(II) atom is coordinated by one pyridine-2,6-dicarboxyl-ate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octa-hedral geometry. Hydrogen-bonding interactions involving the coordinated carboxylate group, 3,5-dimethyl-1H-pyrazole and water help to consolidate the crystal structure.

Project description:In the title compound, [CoCl(2)(C(5)H(9)N(3))(2)], the Co(II) atom adopts a slightly distorted tetra-hedral coordination geometry provided by two chloride anions and two N atoms from the organic ligands.

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-kis(3,5-dimethyl-1H-pyrazole-κN)(nitrato-κO,O')cadmium(II) nitrate.

Project description:The title compound, [Cd(NO(3))(C(5)H(8)N(2))(4)]NO(3), was prepared by reaction of cadmium nitrate and 3,5-dimethyl-pyrazole in ethanol solution. The Cd atom adopts a distorted cis-CdO(2)N(4) octa-hedral geometry involving four dimethylpyrazole molecules and one bidentate nitrate anion. The mol-ecular structure and packing are stabilized by N-H⋯O and C-H⋯O inter- and intra-molecular hydrogen-bonding inter-actions.

Dichloridobis(3,4,5-trimethyl-1H-pyrazole-κN)cobalt(II).

Project description:In the title compound, [Co(II)Cl(2)(C(6)H(10)N(2))(2)], a pair of 3,4,5-trimethyl-pyrazoles act as monodentate ligands. Two Cl(-) anions are also bonded directly to the Co(II) atom, which has a CoN(2)Cl(2) chromophore in a slightly distorted tetra-hedral geometry. The two mol-ecules in the asymmetric unit are related by an approximate twofold rotation roughly parallel to the a axis. The amino H atom in the pyrazole ring participates in weak N-H⋯Cl hydrogen bonds to form chains that propagate roughly parallel to the c axis.

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].

Project description:In the title compound, [Cr(C(15)H(22)BN(6))Cl(2)(C(5)H(8)N(2))]·C(4)H(8)O, the Cr(III) atom is coordinated by three N atoms from the hydro-tris-(3,5-dimethyl-pyrazol-1-yl)borate (Tp*) ligand, one 3,5-dimethyl-pyrazole (Dmpy) N atom and two Cl atoms in a distorted octa-hedral coordination geometry. Two N atoms occupy the axial sites, and the two Cl atoms and other two N atoms from Tp* lie in the equatorial plane. In the crystal, the complex mol-ecules and tetra-hydro-furan solvent mol-ecules are connected via inter-molecular N-H⋯O and C-H⋯O inter-actions.

Dichlorido(3,5-dimethyl-1H-pyrazole)[(3,5-dimethyl-1H-pyrazol-1-yl)(o-tol-yl)methanone]palladium(II).

Project description:In the title compound, [PdCl(2)(C(5)H(8)N(2))(C(12)H(12)N(2)O)], the Pd atom adopts a slightly distorted trans-PdCl(2)N(2) square-planar arrangement. The different Pd-N bond lengths can be related to the the electron-withdrawing effect of the o-toluoyl group on the substituted pyrazole ligand. The complex crystallizes as centrosymmetric hydrogen-bonded dimers through N-H?Cl linkages.

3,5-Dimethyl-4-nitroso-1H-pyrazole.

Project description:In the unit cell of the title compound, C(5)H(7)N(3)O, there are two conformers (A and B) which differ in the position of the oxime group with respect to the protonated pyrazole nitro-gen (trans in the A conformer and cis in the B conformer) and in the geometric parameters. The oxime group exists in the nitroso form in both conformers. In the crystal, mol-ecules are linked by inter-molecular N-H?O and N-H?N hydrogen bonds into zigzag-like chains along the b axis.

Bis(acetato-?O,O')bis-(3,5-dimethyl-1H-pyrazole-?N)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.
