(E)-2-Acetyl-pyrazine 4-nitro-phenyl-hydrazone.

ABSTRACT: In the title compound, C(12)H(11)N(5)O(2), the mol-ecule adopts an E configuration, with the benzene and pyrazine rings located on opposite sides of the N=C double bond. The face-to-face separations of 3.413?(14) and 3.430?(8)?Å, respectively between parallel benzene rings and between pyrazine rings indicate the existence of ?-? stacking between adjacent mol-ecules. The crystal structure also contains N-H?N and C-H?O hydrogen bonding.

In the title compound, C(12)H(11)N(5)O(2), the mol-ecule adopts an E configuration, with the benzene and pyrazine rings located on opposite sides of the N=C double bond. The face-to-face separations of 3.413 (14) and 3.430 (8) Å, respectively between parallel benzene rings and between pyrazine rings indicate the existence of π-π stacking between adjacent mol-ecules. The crystal structure also contains N-H⋯N and C-H⋯O hydrogen bonding. ...[more]

Cyclo-hexa-none 2-nitro-phenyl-hydrazone.

Project description:In the title Schiff base compound, C(12)H(15)N(3)O(2), obtained from a condensation reaction of cyclo-hexa-none and 2-nitro-phenyl-hydrazine, the phenyl-hydrazone group is planar, the largest deviation from the mean plane being 0.0252?(12)?Å, and the nitro fragment is twisted slightly with respect to the mean plane, making a dihedral angle of 6.96?(17)°. The cyclo-heaxanone ring displays a chair conformation. An intra-molecular N-H?O hydrogen bond helps to stabilize the mol-ecular structure.

2-Hydr-oxy-5-nitro-benzaldehyde 2,4-dinitro-phenyl-hydrazone.

Project description:In the title compound, C(13)H(9)N(5)O(7), one of the nitro groups is twisted away from the attached benzene ring by 16.21?(8)°. The dihedral angle between the two benzene rings is 4.63?(1)°. The mol-ecular structure is stabilized by intra-molecular N-H?O and O-H?N hydrogen bonds which generate an S(6) ring motif. The mol-ecules pack as layers parallel to the ab plane; mol-ecules of adjacent layers are linked into chains along the [101] direction through N-H?O hydrogen bonds.

(E)-1-(3-Methoxy-phen-yl)ethanone 4-nitro-phenyl-hydrazone.

Project description:Crystals of the title compound, C(15)H(15)N(3)O(3), were obtained from a condensation reaction of 4-nitro-phenyl-hydrazine and 3-methoxy-acetophenone. In the crystal structure, the methoxy-phenyl ring is twisted slightly with respect to the nitro-phenyl-hydrazine plane, making a dihedral angle of 14.81?(8)°. The nitro and meth-oxy groups are each coplanar with the attached benzene rings. The nitro-phenyl and methoxy-phenyl groups are located on opposite sides of the C=N double bond, indicating an E configuration of the mol-ecule. Adjacent mol-ecules are linked together via N-H?O hydrogen bonding, forming chains along the [101] direction.

(1E)-1-(3-Bromo-phen-yl)ethanone 2,4-di-nitro-phenyl-hydrazone.

Project description:The title compound, C(14)H(11)BrN(4)O(4), contains 3-bromo-phenyl and 2,4-dinitro-phenyl groups on opposite sides of a hydrazone unit and crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the two ring systems in each mol-ecule are 2.0 (1) and 2.5 (4)°. Weak C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-centroid distance = 3.7269 (14) Å] help to establish the packing. Intra-molecular N-H⋯O hydrogen bonds are also observed. On one of the rings, the Br atom is disordered over two equivalent positions of the phenyl ring [occupancy ratio 0.8734 (10):0.1266 (10).

2-Methoxy-benzaldehyde 2,4-dinitro-phenyl-hydrazone.

Project description:In the title compound, C(14)H(12)N(4)O(5), an intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. The dihedral angle between the two benzene rings is 3.91?(3)°, which shows the mol-ecule is almost planar. The para-nitro group is twisted from the benzene ring to which it is attached, making a dihedral angle of 8.50?(9)°. In the crystal structure, mol-ecules are linked together by inter-molecular C-H?O and inter-molecular three-centred O?O [2.8646?(12)-2.9213?(11)?Å] and O?N [3.0518?(11)?Å] inter-actions. The crystal structure is further stabilized by inter-molecular ?-? inter-actions [centroid-to-centroid distances 3.5708?(6)-3.9728?(12)?Å].

Project description:The asymmetric unit of the title compound, C(13)H(8)Cl(2)N(4)O(4), contains two independent but similar and almost planar mol-ecules. An intra-molecular N-H?O hydrogen bond is observed in each mol-ecule.

But-2-enal 2,4-dinitro-phenyl-hydrazone.

Project description:In the title compound, C(10)H(10)N(4)O(4), the but-2-enal chain is almost planar, the largest deviation from the mean plane being 0.013?(1)?Å, and this plane makes a dihedral angle of 9.95?(24)° with the benzene ring,. Of the two nitro groups, one is twisted with respect to the benzene ring, making a dihedral angle of 5.7?(1)°, whereas the other is nearly in the plane of the benzene ring, with a twist angle of only 0.7?(1)°. This difference is related to the occurence of an intra-molecular N-H?O hydrogen bond with the O atom of the less twisted nitro group. The NH group is also involved in a weak inter-action with the same O atom of a symmetry-related mol-ecule, thus forming a pseudo inversion dimer.

3-Penta-none 2,4-dinitro-phenyl-hydrazone.

Project description:Crystals of the title compound, C(11)H(14)N(4)O(4), were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and 3-penta-none. In the crystal structure, the mol-ecule, except one methyl group, displays a nearly planar structure. The imino group links to the adjacent nitro group via intra-molecular hydrogen bonding. The partially overlapped arrangement and face-to-face separation of 3.410?(9)?Å between parallel benzene rings indicate the existence of ?-? stacking between adjacent mol-ecules. The crystal structure also contains weak inter-molecular C-H?O hydrogen bonding.

In the crystal, mol-ecules are linked by weak N-H⋯N inter-actions, forming a zigzag chain running parallel to [001].
