ABSTRACT: In the title compound, C(18)H(15)ClN(6)O(3), the 1,2,3-triazole ring forms dihedral angles of 15.64 (5) and 57.50 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 72.26 (5)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along the b axis. A short O⋯C contact of 2.9972 (13) Å is observed.

Project description:In the title compound, C(12)H(12)N(4)O(4), the 1,2,3-triazole ring and the nitro group form dihedral angles of 37.93?(5) and 8.97?(12)°, respectively, with the phenyl ring.

Project description:In the title compound, C(15)H(9)ClF(3)N(3), the phenyl and chloro-trifluoro-methyl benzene rings are twisted with respect to the planar triazole group, making dihedral angles of 21.29?(12) and 32.19?(11)°, respectively. In the crystal, the mol-ecules pack in a head-to-tail arrangement along the a axis with closest inter-centroid distances between the triazole rings of 3.7372?(12)?Å.

3-(2-Chloro-phen-yl)-4-(4-nitro-phen-yl)-1H-1,2,4-triazole-5(4H)-thione.

Project description:In the crystal structure of the title triazole compound, C(14)H(9)ClN(4)O(2)S, mol-ecules are connected into centrosymmetric dimers by pairs of N-H⋯S hydrogen bonds. In addition, there are weak C-H⋯N hydrogen bonds stabilizing the crystal structure. The dihedral angles between the triazole ring and the two benzene rings are 73.0 (4) and 72.9 (4)°.

5-Methyl-N'-[(3Z)-2-oxo-2,3-dihydro-1H-indol-3-yl-idene]-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide.

Project description:In the title compound, C18H14N6O2, the benzene ring is slightly twisted out of the plane of the 1,2,3-triazole ring (r.m.s. deviation = 0.010?Å), forming a dihedral angle of 6.20?(13)°. The nine non-H ring atoms of the fused five- and six-membered ring system are almost coplanar (r.m.s. deviation = 0.032?Å). The near coplanarity in the central residue is consolidated by an intra-molecular bifurcated N-H?(O,N) hydrogen bond. The conformation about the N=C bond is Z. In the crystal, supra-molecular chains along [101] are sustained by N-H?O hydrogen bonds and C-H?O inter-actions. These are consolidated into a three-dimensional architecture by C-H?? and ?-? inter-actions; the latter occur between centrosymmetrically related 1,2,3-triazole rings [centroid-centroid distance = 3.6056?(14)?Å].

N'-[(E)-1-(5-Chloro-2-hy-droxy-phen-yl)ethyl-idene]pyridine-3-carbohydrazide monohydrate.

Project description:In the title compound, C(14)H(12)ClN(3)O(2)·H(2)O, the benzene ring and the pyridine rings are oriented at a dihedral angle of 57.73 (12)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, the water mol-ecule forms O-H⋯O and O-H⋯N hydrogen bonds to the organic mol-ecule, leading to chains containing R(4) (4)(16) loops. In addition, weak aromatic π-π stacking inter-actions between the centroids of pyridine rings [at distance of 3.864 (2) and 4.013 (2) Å] and C-H⋯π inter-actions occur.

Ethyl 1-[(2-chloro-1,3-thia-zol-5-yl)methyl]-5-methyl-1H-1,2,3-triazole-4-carboxylate.

Project description:In the title compound, C(10)H(11)ClN(4)O(2)S, the triazole ring carries methyl and ethoxy-carbonyl groups and is bound via a methyl-ene bridge to a chloro-thia-zole unit. There is also evidence for significant electron delocalization in the triazolyl system. Intra- and inter-molecular C-H⋯O hydrogen bonds together with strong π-π stacking inter-actions [centroid-centroid distance 3.620 (1) Å] stabilize the structure.

Ethyl 5-amino-1-(4-chloro-2-nitro-phen-yl)-1H-pyrazole-4-carboxyl-ate.

Project description:In the mol-ecule of the title compound, C(12)H(11)ClN(4)O(4), the pyrazole ring is coplanar with the amino and ethoxy-carbonyl groups within 0.026?(2) and 0.105?(2)?Å, respectively. The C(6) ring of the 4-chloro-2-nitro-phenyl group is twisted by 53.58?(4)° relative to the plane of the pyrazole ring. The planar structure of the pyrazole ring is stabilized by an intra-molecular N-H?O hydrogen bond between its substituents. Neighbouring mol-ecules are linked through inter-molecular N-H?N and N-H?O hydrogen bonds, giving rise to one-dimensional tapes along the b axis. Mol-ecules in the chain are linked to those of an adjacent chain through weak C-H?O inter-actions, forming a three-dimensional network.

N'-[1-(4-Nitro-phen-yl)ethyl-idene]acetohydrazide.

Project description:The title compound, C(10)H(11)N(3)O(3), was prepared by the reaction of acetohydrazide and 1-(4-nitro-phen-yl)ethanone. The asymmetric unit contains two crystallographically independent mol-ecules. Inversion-related mol-ecules form dimers, in which two N-H⋯O hydrogen bonds generate an inter-molecular R(2) (2)(8) ring.
