(1E,2E)-1,2-Bis[1-(3-nitro-phen-yl)ethyl-idene]hydrazine.

ABSTRACT: The asymmetric unit of the title compound, C(16)H(14)N(4)O(4), contains one half-mol-ecule of (nitro-phen-yl)ethanimine and the complete mol-ecule is generated by a crystallographic inversion centre. The mol-ecule has an E conformation with respect to each C=N double bond. The central C=N-N=C plane is twisted from the benzene rings with a dihedral angle of 24.76?(11)°. In the crystal, C-H?O inter-actions link the molecules to form sheets that lie parallel to (10-4).

(1E,2E)-1,2-Bis[1-(2-methoxy-phen-yl)ethyl-idene]hydrazine.

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(18)H(20)N(2)O(2). The two mol-ecules exist in an E,E configuration with respect to the two C=N double bonds. The dihedral angles between the two benzene rings in each mol-ecule are 16.89?(6) and 18.84?(6)°. In each mol-ecule, the two meth-oxy groups are coplanar with their attached benzene rings, with r.m.s. deviations of 0.0078 and 0.0336?Å in one mol-ecule, and 0.0163 and 0.0207?Å in the other. An intra-molecular C-H?O hydrogen bond is present in one mol-ecule. In the crystal structure, mol-ecules are arranged into ribbons along the c axis. These ribbons are further stacked along the a axis. The mol-ecules are consolidated by C?N [3.306?(2)-3.427?(2)?Å] and C?O [3.3284?(16)-3.3863?(15)?Å] short contacts. C-H?? inter-actions are also observed.

(1E,2E)-1,2-Bis(2,3-dihydro-1H-inden-1-yl-idene)hydrazine.

Project description:In the title compound, C(18)H(16)N(2), there are two independent half-mol-ecules (A and B) in the asymmetric unit, each mol-ecule being completed by an inversion center situated in the mid-point of the central N-N bond. The mol-ecules themselves therefore are essentially planar with r.m.s. deviations of 0.015?(1) and 0.020?(1)?Å, respectively. In the crystal, mol-ecules are connected via C-H?? inter-actions in which only type B mol-ecules are donors, while both A and B mol-ecules act as acceptors. As a result, type B mol-ecules are linked into infinite chains along b, which are inter-connected by molecules of type A.

(1E,2E)-1,2-Bis(2,3,4-trimeth-oxy-benzyl-idene)hydrazine.

Project description:The title compound, C(20)H(24)N(2)O(6), was obtained as an unexpected product by the reaction of hydrazinium dithio-carbazate with 2,3,4-trimeth-oxy-benzaldehyde in refluxing ethanol. The mol-ecule lies on a center of inversion. The crystal packing is stabilized by weak inter-molecular C-H?O inter-actions.

(E,E)-1,2-Bis[1-(2-bromo-phen-yl)ethyl-idene]hydrazine.

Project description:In the title compound, C(16)H(14)Br(2)N(2), the complete molecule is generated by a crystallographic twofold axis. The dihedral angle between the two benzene rings is 35.28?(8)° and that between the best planes of two ethyl-idinehydrazine N-N=C-Me units is 87.67?(11)°. Each of these N/N/C/C planes makes a dihedral angle of 63.81?(10)° with the adjacent benzene ring. In the crystal, the mol-ecules are arranged into a layer parallel to the ac plane through C-H?? inter-actions. C?Br short contacts [3.4032?(18)-3.5969?(19)?Å] are also observed.

(1E,2E)-1,2-Bis[(1-benzyloxymethyl-1H-indol-3-yl)methylidene]hydrazine.

Project description:The title compound, C(34)H(30)N(4)O(2), lies on an inversion center and consists of two 3-substituted-1H-indole units linked by a 1,2-dimethyl-enehydrazine bridge. It is one of numerous examples in which two aromatic ring systems are joined by this 4-atom bridge. The geometry of the centrosymmetric bridge is: C(arom)-C = 1.444?(3), C=N = 1.284?(3), N-N = 1.414?(4)?Å, C(arom)-C=N = 122.6?(2) and C=N-N = 111.9?(2)°. The nine non-H atoms of the indole unit lie in a plane (?(r.m.s.) = 0.0089?Å) which is twisted 6.0?(2)° with respect to the hydrazine bridge plane. The benzyl-oxymethyl substituents do not lie in the plane of the rest of the mol-ecule and are in a folded rather than an extended conformation. This is described by the three torsion angles in the middle of the C=N-C-O-C(Bz) group, viz. 98.5?(3), -62.1?(3), and -66.3?(2)°.

In the crystal, mol-ecules are linked by C-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.6447?(8)?Å] into a three-dimensional network.

Project description:In the asymmetric unit of the title compound, C(14)H(11)N(5)O(6), there are three crystallographically independent mol-ecules with similar conformations but some differences in bond angles.
