The pyrazole ring [maximum deviations = 0.0049 (17) Å in mol-ecule A and 0.0112 (19) Å in mol-ecule B] makes a dihedral angle of 70.23 (11) and 73.18 (12)° with the phenyl ring in mol-ecules A and B, respectively. The isobutyl group in mol-ecule B is disordered over two sets of sites with...

The asymmetric unit of the title compound, C(11)H(12)N(2)O, consists of two crystallographically independent mol-ecules (A and B) with similar geometries. Both mol-ecules exist in a keto form, the C=O bond length being 1.286 (2) Å in A and 1.283 (2) Å in B. The dihedral angles between the pyrazole ring and the attached phenyl ring are 43.28 (12) and 46.88 (11)°, respectively, for A and B. The e...

The title compound, C(10)H(10)N(2)O, crystallizes with two independent mol-ecules in the asymmetric unit, having closely comparable geometries. The dihedral angles between the 1H-pyrazole and benzene rings in the two mol-ecules are 39.57 (14) and 41.95 (13)°. The two mol-ecules are each connected to neighbouring mol-ecules by pairs of inter-molecular O-H⋯N hydrogen bonds, forming dimers with R(...

The title compound, C(6)H(10)N(2)O, is a zwitterionic pyrazole derivative. The crystal packing is predominantly governed by a three-center iminium-amine N(+)-H⋯O(-)⋯H-N inter-action, leading to an undulating sheet-like structure lying parallel to (100).

The two title compounds, di-mu-bromo-bis{[2,6-bis(pyrazol-1-yl-kappaN(2))pyridine-kappaN](perchlorato-kappaO)copper(II)}, [Cu(2)Br(2)(ClO(4))(2)(C(11)H(9)N(5))(2)], (I), and [2,6-bis(pyrazol-1-yl)pyridine]dibromocopper(II), [CuBr(2)(C(11)H(9)N(5))], (II), were synthesized by only slight modifications of the same reaction; compound (II) was formed by adding one molar equivalent of pyrazole (C(3)...

The title compound, [Co(C(10)H(10)BF(6)N(4))(C(15)H(13)BF(9)N(6))], is a polymorph of the previously reported neutral cobalt(II) complex [Stibrany & Potenza (2010 ▶). Acta Cryst. E66, m506-m507], which contains one each of the monoanionic ligands, bis-[5-methyl-3-(trifluoro-meth-yl)pyrazol-1-yl]borate (Bp) and tris-[5-methyl-3-(trifluoro-meth-yl)pyrazol-1-yl]borate (Tp). A distorted octahedral ...

The asymmetric unit of the title compound, C(25)H(14)ClFN(4)S, contains two independent mol-ecules (A and B). Each mol-ecule consists of five rings, namely chloro-phenyl, fluoro-phenyl, 1H-pyrazole, thia-zole and benzonitrile. In mol-ecule A, the 1H-pyrazole ring makes dihedral angles of 52.54 (8), 35.96 (8) and 15.43 (8)° with respect to the attached chloro-phenyl, fluoro-phenyl and thia-zole ...

In the crystal structure of the title compound, C(20)H(14)FN(5)O(2), the pyrazole ring forms dihedral angles of 59.3 (2), 25.6 (2) and 46.0 (2)° with the directly attached 4-fluoro-phenyl, pyridine and nitro-phenyl rings, respectively. The crystal packing is characterized by inter-molecular N-H⋯N and N-H⋯O hydrogen bonds.
