(1Z)-1-[(2E)-3-(4-Bromo-phen-yl)-1-(4-fluoro-phen-yl)prop-2-en-1-yl-idene]-2-(2,4-dinitro-phen-yl)hydrazine.

ABSTRACT: In the title mol-ecule, C(21)H(14)BrFN(4)O(4), the mean planes of the two nitro groups form dihedral angles of 3.1 (2) and 7.1 (5)° with the benzene ring to which they are attached. The dinitro-substituted ring forms dihedral angles of 8.6 (2) and 71.9 (2)° with the bromo- and fluoro-substituted benzene rings, respectively. The dihedral angle between the bromo- and fluoro-substituted benzene rings is 80.6 (2)°. There is an intra-molecular N-H⋯O hydrogen bond. In the crystal, pairs of weak C-H⋯O hydrogen bonds form inversion dimers. In addition, π-π stacking inter-actions between the bromo- and dinitro-substituted rings [centroid-centroid separation = 3.768 (2) Å] are observed.

1-[(Bromo-meth-yl)(phen-yl)meth-ylene]-2-(2,4-dinitro-phen-yl)hydrazine.

Project description:The title compound, C(14)H(11)BrN(4)O(4), comprises two crystallographically independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule B, intra-molecular bifurcated N-H⋯O and N-H⋯Br hydrogen bonds and in mol-ecule A, an intra-molecular N-H⋯O hydrogen bond generate S(6) ring motifs. The dihedral angle between the phenyl and benzene rings is 5.44 (6) in mol-ecule A and 7.63 (6)° in mol-ecule B. The ortho- and meta-nitro substituents make dihedral angles of 6.67 (15) and 2.26 (15)° to the attached benzene ring in mol-ecule A and 6.37 (17) and 5.81 (16)° in mol-ecule B. The Br atom in mol-ecule B is disordered over two positions with a refined site-occupancy ratio of 0.61 (3):0.39 (3). Inter-esting features of the crystal structure are the short Br⋯N [3.257 (3)-3.294 (4) Å], Br⋯O [3.279 (3)-3.307 (4) Å] and O⋯O [2.9319 (16)-2.9995 (16) Å] contacts, which are shorter than the sum of the van der Waals radii of these atoms. The crystal structure is further stabilized by inter-molecular C-H⋯O and π-π inter-actions [centroid-centroid distances = 3.6643 (8)-3.8514 (8) Å].

(E)-1-(2,4-Dinitro-phen-yl)-2-[1-(3-fluoro-phen-yl)ethyl-idene]hydrazine.

Project description:The mol-ecule of the title hydrazone derivative, C(14)H(11)FN(4)O(4), is nearly planar, with a dihedral angle between the benzene rings of 3.71 (7)°. The central ethyl-idenehydrazine N-N=C-C plane makes dihedral angles of 5.32 (10) and 9.02 (10)° with the 2,4-dinitro- and 3-fluoro-substituted benzene rings, respectively. An intra-molecular N-H⋯O bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions into a sheet parallel to (10-1). The mol-ecules are further stacked along the a axis by π-π inter-actions with centroid-centroid distances of 3.6314 (9) and 3.7567 (10) Å. A C⋯F short contact [2.842 (3) Å] is observed. The 3-fluoro-phenyl group is disordered over two orientations with a site-occupancy ratio of 0.636 (3):0.364 (3).

(E)-1-(2,4-Dinitro-phen-yl)-2-[1-(4-fluoro-phen-yl)ethyl-idene]hydrazine.

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.

Project description:In the title compound, C(13)H(9)FN(4)O(4), the dihedral angle between the mean planes of the two benzene rings of the nearly planar mol-ecule is 6.6 (9)°. The dihedral angles between the mean planes of the benzene ring and its two attached nitro groups are 6.7 (7) and 7.2 (9)°. Crystal packing is stabilized by N-H⋯O hydrogen bonds, weak C-H⋯O and C-H⋯F inter-molecular inter-actions and centroid-centroid π-ring stacking inter-actions.

(2E)-1-(4-Bromo-phen-yl)-3-(4-fluoro-phen-yl)prop-2-en-1-one.

Project description:The title compound, C(15)H(10)BrFO, is isostructural with (2E)-1-(4-chloro-phen-yl)-3-(4-fluoro-phen-yl)prop-2-en-1-one [Qiu et al. (2006 ▶). Acta Cryst. E62, o3525-o3526], but the structures of other dihalogen analogues, without fluorine, are different, although they are also isostructural within the series. The mol-ecule is approximately flat, the dihedral angle between the ring planes being 8.49 (13)°. In the crystal structure, inter-molecular C-H⋯O, C-H⋯F and C-H⋯Br hydrogen bonds link mol-ecules into V-shaped ribbons running parallel to [101] and stacked with an inter-planar distance of approximately 3.53 Å (centroid-vcentroid distance = 3.857 Å)..

(2E)-1-(2-Bromo-phen-yl)-3-(4-bromo-phen-yl)prop-2-en-1-one.

Project description:The title compound, C(15)H(10)Br(2)O, is a chalcone with 2-bromo-phenyl and 4-bromo-phenyl rings bonded to opposite sides of a propenone group. The dihedral angle between mean planes of the benzene rings is 71.3 (1)°. The angle between the mean plane of the prop-2-ene-1-one group and the mean planes of the 2-bromo-phenyl and 4-bromo-phenyl rings are 64.2 (9) and 71.3 (1)°, respectively. A weak inter-molecular C-H⋯O inter-action and two weak C-Br⋯π inter-actions are observed, which contribute to the stability of the crystal packing.

(2E)-3-(2-Fluoro-phen-yl)-1-(4-fluoro-phen-yl)prop-2-en-1-one.

Project description:In the title compouund, C(15)H(10)F(2)O, the mol-ecule exists in an E conformation with respect to the C=C bond [1.3382 (16) Å]. The dihedral angle between the fluoro-substituted benzene rings is 6.80 (6)° and the whole mol-ecule is roughly planar (r.m.s. deviation for the non-H atoms = 0.069 Å). In the crystal, mol-ecules are linked by C-H⋯F and C-H⋯O inter-actions into sheets lying parallel to the bc plane.

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.

N-(2,4-Dinitro-phen-yl)-N'-[nitro-(phenyl)-methyl-ene]hydrazine.

Project description:The title compound, C(13)H(9)N(5)O(6), contains three nitro groups. It is prepared by the reaction of benzaldehyde 2,4-dinitro-phenyl-hydrazone with nitric oxide at ambient temperature. The imine group is nearly coplanar with the (2,4-dinitro-phen-yl)-hydrazine unit. The second benzene ring and the third nitro group are twisted away from this plane, with dihedral angles of 48.5 (3) and 15.2 (3)°, respectively. Weak intra-molecular N-H⋯O inter-actions are observed.
