(E)-1-(2-Nitro-benzyl-idene)-2-phenyl-hydrazine.

ABSTRACT: The asymmetric unit of the title compound, C(13)H(11)N(3)O(2), contains two mol-ecules with slightly different conformations: the dihedral angle between the aromatic rings is 13.01?(10)° in one mol-ecule and 14.05?(10)° in the other. Both mol-ecules feature short intra-molecular C-H?O contacts, which generate S(6) rings. In the crystal, both mol-ecules form inversion dimers linked by pairs of N-H?O hydrogen bonds, thereby generating R(2) (2)(16) rings.

In the crystal, C-H?? inter-actions and C-H?O hydrogen bonds are observed growing along the a, b and c axes, resulting in a complex supramolecular array.

Project description:The asymmetric unit of the title compound, C(13)H(11)ClN(2), contains two geometrically distinct mol-ecules; one mol-ecule is close to planar [dihedral angle between the aromatic rings = 2.44 (18)°] and the other is twisted about the linking hydrazide group [dihedral angle = 14.08 (19)°]. In the crystal, the N-H groups do not form hydrogen bonds and the mol-ecules are linked by weak C-H⋯π inter-actions.

(E)-1-(4-Nitro-phen-yl)-2-(4-{[(E)-2-(4-nitro-phen-yl)hydrazinyl-idene]meth-yl}benzyl-idene)hydrazine dihydrate.

Project description:The 30 non-H atoms in title dihydrazine compound, C(20)H(16)N(6)O(4)·2H(2)O, are close to coplanar, the r.m.s. deviation for these atoms being 0.096?Å. The conformation about each of the C=N bonds is E, and the mol-ecule has non-crystallographic 2/m symmetry. The presence of O-H?O and N-H?O hydrogen bonding leads to a three-dimensional network in the crystal structure. A highly disordered solvent mol-ecule is present within a mol-ecular cavity defined by the organic and water mol-ecules. Its contribution to the electron density was removed from the observed data in the final cycles of refinement and the formula, molecular weight and density are given without taking into account the contribution of the solvent molecule.

1-(2,4-Di-nitro-phen-yl)-2-[(E)-(3,4,5-tri-meth-oxy-benzyl-idene)]hydrazine.

Project description:Mol-ecules of the title compound, C16H16N4O7, are not planar with a dihedral angle of 5.50 (11)° between the substituted benzene rings. The two meta-meth-oxy groups of the 3,4,5-tri-meth-oxy-benzene moiety lie in the plane of the attached ring [Cmeth-yl-O-C-C torsion angles -0.1 (4)° and -3.7 (3)°] while the para-meth-oxy substituent lies out of the plane [Cmeth-yl-O-C-C, -86.0 (3)°]. An intra-molecular N-H⋯O hydrogen bond involving the 2-nitro substituent generates an S(6) ring motif. In the crystal structure, mol-ecules are linked by weak C-H⋯O inter-actions into screw chains, that are arranged into a sheet parallel to the bc plane. These sheets are connected by π-π stacking inter-actions between the nitro and meth-oxy substituted aromatic rings with a centroid-centroid separation of 3.9420 (13) Å. C-H⋯π contacts further stabilize the two-dimensional network.

1-(2,4-Di-nitro-phen-yl)-2-[(E)-2,4,5-tri-meth-oxy-benzyl-idene]hydrazine.

Project description:The title compound, C16H16N4O7, is close to being planar, with a dihedral angle of 3.15 (11)° between the benzene rings. The meth-oxy groups at the ortho- and para-positions of the 2,4,5-tri-meth-oxy-phenyl group are almost coplanar with the ring [deviations of the C atoms = 0.017 (2) and -0.025 (2) Å, respectively], whereas the meta-meth-oxy group deviates slightly [C-atom displacement = 0.162 (2) Å]. Both the ortho- and para-nitro groups are close to being coplanar with their attached ring [dihedral angles = 7.81 (12) and 8.56 (11)°, respectively]. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds involving the same H atom as the intra-molecular bond generate R 2 (2)(12) loops. The dimers are linked by weak C-H⋯O inter-actions into sheets parallel to the (10-4) plane and the sheets are stacked by π-π inter-actions, with a centroid-centroid distance of 3.5974 (14) Å.
