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

ABSTRACT: 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.

Project description:In the title mol-ecule, C(12)H(14)N(2), the dihedral angle between the pyrazole and phenyl ring mean planes is 78.65 (19)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into chains along [010].

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].

3,5-Dimethyl-1-phenyl-1H-pyrazole-4-carbaldehyde.

Project description:In the title mol-ecule, C(12)H(12)N(2)O, the five- and six-membered rings form a dihedral angle of 68.41?(16)°. The aldehyde group is nearly coplanar with the pyrazole ring [C-C-C-O torsion angle = -0.4?(5)°]. The three-dimensional architecture is sustained by weak C-H?O and C-H?? inter-actions.

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

Project description: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.

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.

Dimethyl 1-cyano-methyl-1H-pyrazole-3,5-dicarboxyl-ate.

Project description:The title mol-ecule, C(9)H(9)N(3)O(4), syhthesized from 1H-pyrazole-3,5-dicarboxylic acid and 2-bromo-acetonitrile, is approximately planar; the inter-planar angles between the pyrazole ring and the mean planes of the two carboxylate units and the cyanomethyl unit are 4.49?(10), 5.56?(9) and 5.03?(19)°, respectively. In the crystal, inversion dimers linked by pairs of weak C-H ?O bonds occur, and the packing is further stabilized by aromatic ?-? stacking [centroid-centroid separation = 3.793?(4)?Å].

3,5-Dimethyl-1-(4-nitro-phen-yl)-1H-pyrazole.

Project description:In the title pyrazole derivative, C(11)H(11)N(3)O(2), the benzene ring is twisted [dihedral angle = 31.38 (12)°] with respect to the pyrazole ring (r.m.s. deviation = 0.009 Å). The nitro group is effectively coplanar with the benzene ring to which it is attached [O-N-C-C torsion angle = -6.5 (3)°]. Supra-molecular chains along the b axis are formed owing to π-π inter-actions [3.8653 (2) Å] between translationally related mol-ecules involving both the five- and six-membered rings.

Dimethyl 1-(4-cyano-benz-yl)-1H-pyrazole-3,5-dicarboxyl-ate.

Project description:The title compound, C(15)H(13)N(3)O(4), was synthesized from dimethyl 1H-pyrazole-3,5-dicarboxyl-ate and 4-(bromo-meth-yl)benzonitrile.

One of the methyl groups is disordered over two positions of equal occupancy.
