ABSTRACT: There are two mol-ecules in the asymmetric unit of the title compound, C(12)H(11)BrN(4)O. The dihedral angles between the pyrazole and pyrimidine rings are 1.28?(17) and 1.56?(17)° in the two mol-ecules. In one of the mol-ecules, the but-3-yn-yloxy side chain is disordered over two sets of sites in a 0.714?(8):0.286?(8) ratio.

There are two mol-ecules in the asymmetric unit of the title compound, C(12)H(11)BrN(4)O. The dihedral angles between the pyrazole and pyrimidine rings are 1.28 (17) and 1.56 (17)° in the two mol-ecules. In one of the mol-ecules, the but-3-yn-yloxy side chain is disordered over two sets of sites in a 0.714 (8):0.286 (8) ratio. ...[more]

Project description:In the title compound, C(10)H(9)N(5), the fused 2-methyl-imidazo[1,2-a]pyrimidine ring system is approximately planar [dihedral angle of 1.14?(9)° between the two fused rings] and the 1H-pyrazole ring is rotated by 28.16?(11)° out of that plane.

5-Bromo-2-[5-(4-nitro-phen-yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]pyrimidine.

Project description:In the title pyrazoline compound, C(19)H(14)BrN(5)O(2), the essentially planar pyrazoline and pyrimidine rings [maximum deviations = 0.013 (1) and 0.009 (1) Å, respectively] are inclined slightly to one another, making a dihedral angle of 10.81 (10)°. The nitro-benzene unit is almost perpendicular to the attached pyrazoline ring, as indicated by the dihedral angle of 84.61 (8)°. In the crystal structure, inter-molecular C-H⋯N contacts link the mol-ecules into dimers in an anti-parallel manner. These dimers are further linked into one-dimensional chains along the b axis via C-H⋯O contacts. The crystal structure is consolidated by three different inter-molecular π-π inter-actions [range of centroid-centroid distances = 3.5160 (11)-3.6912 (11) Å].

(2E)-2-{[3-Methyl-5-(2-naphth-yloxy)-1-phenyl-1H-pyrazol-4-yl]methyl-idene}hydrazinecarbothio-amide monohydrate.

Project description:In the title compound, C(22)H(19)N(5)OS·H(2)O, the naphthalene ring system and the benzene ring [dihedral angle = 85.19?(8)°] make dihedral angles of 87.02?(9) and 14.41?(10)°, respectively, with the pyrazole ring. The mean plane through the 2-methyl-enehydrazinecarbothio-amide group [C-N-N-C(=S)-N; maximum deviation = 0.022?(1)?Å] is slightly twisted from the pyrazole ring [dihedral angle = 5.60?(11)°]. In the crystal, mol-ecules are linked by N-H?S, N-H?O, O-H?S, O-H?N and C-H?S hydrogen bonds into sheets parallel to the ab plane. ?-? inter-actions are also observed [centroid-to-centroid distances = 3.7778?(12) and 3.7010?(12)?Å].

3-Bromo-6-nitro-1-(prop-2-yn-yl)-1H-indazole.

Project description:In the title compound, C(10)H(6)BrN(3)O(2), the indazole fused-ring system is nearly planar (r.m.s. deviation = 0.008 Å); its nitro substituent is nearly coplanar with the fused ring [dihedral angle = 4.5 (2)°]. In the crystal, adjacent mol-ecules are linked by weak acetyl-ene-nitro C-H⋯O hydrogen bonds, generating a helical chain running along the b axis.

Project description:The molecule of the title compound, C(12)H(8)ClF(3)N(4)O, is twisted as indicated by the C-O-C-C torsion angle of 76.9 (3)°.

4-{1-[4-(4-Bromo-phen-yl)-1,3-thia-zol-2-yl]-5-(4-fluoro-phen-yl)-4,5-dihydro-1H-pyrazol-3-yl}-5-methyl-1-(4-methyl-phen-yl)-1H-1,2,3-triazole.

Project description:In the title compound, C(28)H(22)BrFN(6)S, the central pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The dihedral angles between the least-squares plane through this ring and the adjacent thia-zole [18.81?(15)°] and triazole [1.83?(16)°] rings indicate a twist in the mol-ecule. A further twist is evident by the dihedral angle of 64.48?(16)° between the triazole ring and the attached benzene ring. In the crystal, C-H?N, C-H?F, C-H?? and ?-? inter-actions [occurring between the thia-zole and triazole rings, centroid-centroid distance = 3.571?(2)?Å] link mol-ecules into a three-dimensional architecture. The sample studied was a non-merohedral twin; the minor twin component refined to 47.16?(7)%.

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(18)H(12)Br(2)N(2)O. In each mol-ecule, one of the bromo-phenyl rings lies almost in the plane of pyrazole unit [dihedral angles of 5.8 (3)° in the first mol-ecule and and 5.1 (3)° in the second] while the other ring is approximately perpendicular to it [dihedral angles of 80.3 (3) and 76.5 (3)°]. The crystal packing shows inter-molecular C-H⋯O inter-actions. The crystal studied was a racemic twin.

5-Methyl-1-[(4-methyl-phen-yl)sulfon-yl]-1H-pyrazol-3-yl 4-methyl-benzene-sulfonate.

Project description:In the title compound, C(18)H(18)N(2)O(5)S(2), the tolyl rings are oriented at a dihedral angle of 16.15 (11)° with respect to one another. The 5-methyl-1H-pyrazol-3-ol ring is roughly planar (r.m.s. deviation = 0.0231 Å) and subtends angles of 73.82 (8) and 89.85 (8)° with the tolyl rings. In the crystal, very weak π-π inter-actions between tolyl groups, with centroid-centroid distances of 4.1364 (19) and 4.0630 (16) Å, together with a C-H⋯π contact generate a three-dimensional network.
