4-{[2-(2,4-Dinitro-phen-yl)hydrazinyl-idene](phen-yl)meth-yl}-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one ethanol monosolvate.

ABSTRACT: In the title compound, C23H18N6O5·C2H6O, all three benzene rings lie in an approximate plane [maximum deviation = 0.2688 (16) Å] that makes an angle of 53.56 (3)° with the plane of the pyrazolone ring. Intra-molecular N-H⋯O hydrogen bonds occur. In the crystal, the ethanol solvent mol-ecule links adjacent mol-ecules through N-H⋯O-H⋯O hydrogen bonds, leading to an infinite chain along the c-axis direction. The ethyl group of the ethanol solvent mol-ecule is disordered over two set of sites in a 0.762 (5):0.238 (5) ratio.

4-{[2-(2,4-Dinitro-phen-yl)hydrazinyl-idene]meth-yl}phenol ethanol hemisolvate.

Project description:In the title compound, C(13)H(10)N(4)O(5)·0.5C(2)H(5)OH, the two benzene rings form a dihedral angle of 4.29?(9)°. The ethanol solvent mol-ecule was treated as disordered between two orientations related by symmetry (center of inversion), with occupancies fixed at 0.5. The crystal packing, stabilized by inter-molecular O-H?O and N-H?O hydrogen bonds and ?-? inter-actions [indicated by the short distance of 3.7299?(7)?Å between the centroids of benzene rings from neighbouring mol-ecules], exhibits short inter-molecular O?O contacts of 2.8226?(3)?Å.

(Z)-4-[2-(2,4-Dimethyl-phen-yl)hydrazinyl-idene]-3-methyl-pyrazol-5(1H)-one.

Project description:The mol-ecule of the title compound, C12H14N4O, is roughly planar, with a dihedral angle of 8.0?(8)° between the benzene and pyrazole rings, and an intra-molecular N-H?O hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules are linked into an inversion dimer by a pair of N-H?O hydrogen bonds, which form an R 2 (2)(8) ring motif.

Project description:The asymmetric unit of the title compound, C(12)H(12)F(2)N(2)O(3), contains two mol-ecules, both of which exist in an E conformation with respect to their C=N bonds [1.321?(6) and 1.310?(6)?Å]. The mol-ecular conformations are supported by intra-molecular N-H?O hydrogen bonds, which generate S(6) rings. In the crystal, mol-ecules are linked by C-H?O and C-H?F hydrogen bonds into layers lying parallel to (001). The crystal studied was an inversion twin with a 0.58?(1):0.42?(1) domain ratio.

Project description:The title mol-ecule, C(14)H(11)ClN(4)O(4), is in an E configuration and is twisted with the dihedral angle between the two benzene rings being 38.48?(8)°. The ethyl-idenehydrazine plane makes dihedral angles of 6.03?(10) and 44.04?(11)°, respectively, with the dinitro- and chloro-substituted benzene rings. The two nitro groups are essentially coplanar with the bound benzene ring, making dihedral angles of 0.9?(2) and 1.65?(18)°. An intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by a weak C-H?O inter-action into a chain along the c axis. The chains are further stacked along the b axis by a ?-? inter-action with a centroid-centroid distance of 3.6088?(10)?Å.

Project description:The mol-ecule of the title compound, C(12)H(10)N(4)O(4)S, is slightly twisted, with a dihedral angle of 8.23?(9)° between the benzene and thio-phene rings. One nitro group is co-planar [O-N-C-C torsion angles = -0.5?(3) and -1.9?(3)°] whereas the other is slightly twisted with respect to the benzene ring [O-N-C-C torsion angles = -5.1?(3) and -5.7?(3)°]. In the crystal, the mol-ecules are linked by weak C-H?O inter-actions into screw chains along the b axis. The mol-ecular conformation is consolidated by an intra-molecular N-H?O hydrogen bond.

Project description:The title compound, C(14)H(11)FN(4)O(4), crystallizes with two essentially planar mol-ecules in the asymmetric unit; the dihedral angles between the benzene rings are 1.57?(15) and 6.17?(15)°. In each mol-ecule, an intra-molecular N-H?O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by weak C-H?O and C-H?F inter-actions into sheets lying parallel to (120). O?C [2.980?(4)?Å] and O?N [2.892?(3)?Å] short contacts also occur.

1-(2-Chloro-benzyl-idene)-2-(2,4-dinitro-phen-yl)hydrazine.

Project description:In the title compound, C(13)H(9)ClN(4)O(4), there are two crystallographically independent mol-ecules in the asymmetric unit, which have very similar conformations. The C=N-N angles in each independent mol-ecule are 115.0?(2) and 116.6?(2)°, which are significantly smaller than the ideal value of 120° expected for sp(2)-hybridized N atoms. This is probably a consequence of repulsion between the nitro-gen lone pairs and the adjacent N-N bonds. Two bifurcated intra-molecular N-H?O hydrogen bonds help to establish the mol-ecular conformation and consolidate the crystal packing.

Project description:The title compound, C(20)H(16)N(4)O(4), contains two crystallographically independent mol-ecules (A and B) in the asymmetric unit. Intra-molecular N-H?O hydrogen bonds generate S(6) ring motifs in both molecules. The dihedral angles between the nitro-substituted benzene rings and the two benzene rings in mol-ecules A and B are 14.32?(9), 17.89?(9)° and 13.04?(9) and 25.71?(9)°. The ortho and para nitro groups form dihedral angles of 6.2?(2) and 8.5?(2)° in mol-ecule A, and 5.3?(3) and 13.8?(2)° in mol-ecule B, with the benzene rings to which they are attached. The crystal structure is stabilized by inter-molecular C-H?O inter-actions.
