(2E)-2-(2-Phenyl-hydrazin-1-yl-idene)propanoic acid.

ABSTRACT: The 13 non-H atoms comprising the title compound, C(9)H(10)N(2)O(2), are close to planar (r.m.s. deviation = 0.140?Å), with maximum deviations of 0.292?(1) and 0.210?(1)?Å to either side of the least-squares plane exhibited by the hy-droxy and carbonyl O atoms, respectively. The observed conformation is stabilized by an intra-molecular O-H?N hydrogen bond. The conformation about the N=C double bond [1.2909?(16)?Å] is E. The hy-droxy OH group also forms an inter-molecular hydrogen bond to a carbonyl O atom, and the amine H atom similarly forms an N-H?O hydrogen bond to a second carbonyl O atom. The result is the formation of a double layer with a flat topology. Layers stack along the a-axis direction connected by C-H?? inter-actions.

The 13 non-H atoms comprising the title compound, C(9)H(10)N(2)O(2), are close to planar (r.m.s. deviation = 0.140 Å), with maximum deviations of 0.292 (1) and 0.210 (1) Å to either side of the least-squares plane exhibited by the hy-droxy and carbonyl O atoms, respectively. The observed conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. The conformation about the N=C double bond [1.2909 (16) Å] is E.

N'-[(1E,2E)-1-(2-Phenyl-hydrazin-1-yl-idene)-1-(phenyl-sulfon-yl)propan-2-yl-idene]benzohydrazide.

Project description:The configuration about each C=N bond in the title compound, C(22)H(20)N(4)O(3)S, is E. While to a first approximation the phenyl-hydrazin-1-yl-idene and benzohydrazide residues are coplanar, in part due to the presence of an intra-molecular N-H?N hydrogen bond, significant twists are evident in the orientations of the hydrazine [N-N-C-C torsion angle = -170.74?(11)°] and benzoyl benzene [N-C-C-C = -21.72?(18)°] rings. The sulfonyl benzene ring occupies a position almost normal to the rest of the mol-ecule [C-S-C-N = -92.28?(10)°]. Centrosymmetric aggregates mediated by pairs of hydrazide-sulfonyl N-H?O hydrogen bonds are the predominant packing motif in the crystal. These are connected into linear supra-molecular chains via C-H?O inter-actions which are, in turn, linked into layers in the ac plane via C-H?? inter-actions. Connections between layers along the b-axis direction are of the ?-? type and occur between centrosymmetrically related hydrazine-bound benzene rings [centroid-centroid separation = 3.7425?(9)?Å].

(1E,2E)-1,2-Bis(2,2-diphenyl-hydrazin-1-yl-idene)ethane.

Project description:In the crystal structure of the title compound, C(26)H(22)N(4), the mol-ecule is located on an inversion centre and shows an E configuration with respect to each C=N bond. The dihedral angle between the phenyl rings in the diphenyl-hydrazone group is 83.69 (11)°. These two rings make dihedral angles of 30.53 (15) and 84.53 (16)° with the central N-N=C-C=N-N dihydrazonoethane plane. Inter-molecular C-H⋯π inter-actions are observed.

Project description:In the title compound, C20H18BrN3S, the cyclo-pentane ring adopts a half-chair conformation. The 4-bromo-phenyl and phenyl rings make dihedral angles of 34.6?(1) and 68.52?(6)°, respectively, with the di-hydro-thia-zole ring. In the crystal, the mol-ecules pack in sheets approximately parallel to (101) which are formed by weak C-H?Br inter-actions.

(2E)-2-[2-(Cyclo-hexyl-carbamothio-yl)hydrazinylidene]-propanoic acid.

Project description:In the title thio-urea derivative, C(10)H(17)N(3)O(2)S, the carboxyl group and the least-squares plane through the cyclo-hexyl ring are twisted out of the plane through the central CN(3)S residue; the respective dihedral angles are 7.18?(8) and 62.29?(4)°. The conformation about the azomethine bond [1.275?(2)?Å] is E. The NH groups are anti, with one forming an intra-molecular N-H?N hydrogen bond. The main feature of the crystal structure is the formation of linear supra-molecular chains along [110] mediated by alternating pairs of O-H?O and pairs of N-H?S hydrogen bonds.

4-[(2E)-2-(2-Hy-droxy-benzyl-idene)hydrazin-1-yl]benzonitrile.

Project description:The asymmetric unit of the title Schiff base, C(14)H(11)N(3)O, contains two independent mol-ecules which have similar conformations. The dihedral angles between the benzene rings are 4.19?(9) and 14.18?(9)° in the two mol-ecules. An intra-molecular O-H?N hydrogen bond stabilizes the mol-ecular conformation of each mol-ecules. The crystal packing is dominated by pairs of equivalent N-H?N and C-H?O hydrogen bonds which arrange the mol-ecules into layers parallel to (-111).

(2E)-2-[2-(4-Chloro-phen-yl)hydrazin-1-yl-idene]-4,4,4-trifluoro-3-oxobutanal.

Project description:The title compound, C(10)H(6)ClF(3)N(2)O(2), was synthesized by coupling 4-dimethyl-amino-1,1,1-trifluoro-but-3-en-2-one with 4-chloro-benzene-diazo-nium chloride. It crystallizes with two mol-ecules in the asymmetric unit, which form two similar centrosymmetric dimers via hydrogen bonds. Extensive electron delocalization and intra-molecular N-H⋯O hydrogen bonds are responsible for a planar conformation of the mol-ecules (maximum deviations = 0.010 and -0.015 Å for the two molecules). In addition to hydrogen bonds, π-π stacking inter-actions with centroid-centroid distances of 3.604 (2) and 3.583 (2) Å contribute to the stability of the crystal structure.

(E)-1-Phenyl-2-({5-[(1E)-(2-phenyl-hydrazin-1-yl-idene)meth-yl]-2-thien-yl}methyl-idene)hydrazine.

Project description:The title mol-ecule, C(18)H(16)N(4)S, adopts a U-shape with the aromatic groups lying syn and orientated in the same direction as the thio-phene S atom. The conformation about each of the C=N bonds is E. Overall, the mol-ecule is curved as seen in the dihedral angle of 30.26 (19)° formed between the terminal benzene rings. In the crystal, supra-molecular chains along the c axis are formed by a combination of N-H⋯N hydrogen bonds and N-H⋯π inter-actions.

(1Z,2E)-N'-{1-[2-(4-Bromo-phen-yl)hydrazin-1-yl-idene]-1-chloro-propan-2-yl-idene}thio-phene-2-carbohydrazide.

Project description:In the title compound, C(14)H(12)BrClN(4)OS, the thienyl ring is disordered over two orientations with a site-occupancy ratio of 0.853 (2):0.147 (2). The mol-ecule is roughly planar, with the dihedral angles between the thienyl and benzene rings being 6.24 (16) and 9.7 (11)° for the major and minor components, respectively. The central fragment is almost planar [r.m.s. deviation = 0.0275 (2) Å for the ten non-H atoms]. The mean plane through this middle unit makes a dihedral angle of 2.71 (7)° with the benzene ring, whereas these values are 4.46 (15) and 7.7 (11)° for the major and minor components of the thienyl ring, respectively. In the crystal, mol-ecules are linked into dimers by pairs of N-H⋯O hydrogen bonds, forming R(2) (2)(8) ring motifs. These dimers are arranged into sheets parallel to the ac plane.

Project description:The title compound, C(11)H(13)N(3)S, is close to being planar, with a dihedral angle of 9.64?(3)° between the benzene ring and the thio-semicarbazone mean plane, maintained by the presence of ?-conjugation in the chain linking the the two systems. In the crystal, N-H?S hydrogen bonds form centrosymmetric dimers through a cyclic association [graph-set R(2) (2)(8)].

3-[(2E)-2-(Butan-2-yl-idene)hydrazin-yl]-6-chloro-pyridazine.

Project description:The asymmetric unit of the title compound, C(8)H(11)ClN(4), contains two independent mol-ecules (A and B) with slightly different conformations: the dihedral angles between the 3-chloro-6-hydrazinylpyridazine units and butyl side chains are 4.5?(2) and 11.98?(16)°. In the crystal, the A and B mol-ecules are linked by a pair of N-H?N hydogen bonds, generating an R(2) (2)(8) loop.
