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

ABSTRACT: 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?? inter-actions.

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. ...[more]

(E)-1-(3-Nitro-phen-yl)-2-({5-[(1E)-2-(3-nitro-phen-yl)hydrazin-1-ylidenemeth-yl]-2-thien-yl}methyl-idene)hydrazine.

Project description:The title mol-ecule, C(18)H(14)N(6)O(4)S, adopts a U-shape with the aromatic groups lying syn and oriented in the same direction as the thio-phene S atom. Twists away from planarity are evident with the maximum deviation being found for a terminal nitro group: C/C/N/O = 19.0?(3)°. The conformation about each of the C=N bonds is E. In the crystal, centrosymmetrically related mol-ecules are connected via N-H?O(nitro) hydrogen bonds, forming 14-membered {?HNC(3)NO}(2) synthons. These are linked into layers via C-H?O(nitro) inter-actions with the primary inter-actions between layers being of the type C-H??, where the ?-system is the thio-phene ring.

Benzoic acid-4-{(1E)-[(E)-2-(pyridin-4-yl-methyl-idene)hydrazin-1-yl-idene]meth-yl}pyridine (2/1).

Project description:In the title co-crystal, C(12)H(10)N(4)·2C(7)H(6)O(2), the complete 4-pyridine-aldazine mol-ecule is generated by a crystallographic centre of inversion. In the crystal, mol-ecules are connected into a three component aggregate via O-H?N hydrogen bonds. As both the benzoic acid [O-C-C-C torsion angle = 174.8?(2)°] and 4-pyridine-aldazine (r.m.s. deviation of the 16 non-H atoms = 0.041?Å) mol-ecules are almost planar, the resulting three-component aggregate is essentially planar. The crystal packing comprises layers of the three-component aggregates of alternating orientation stacked along the b axis; the connections between the mol-ecules are of the types C-H?? and ?-? [pyridine-benzene centroid-centroid distance = 3.787?(4)?Å].

2-[(1E)-[(Z)-2-({[(1Z)-[(E)-2-[(2-Hy-droxy-phen-yl)methyl-idene]hydrazin-1-yl-idene]({[(4-methyl-phen-yl)meth-yl]sulfan-yl})meth-yl]disulfan-yl}({[(4-methyl-phen-yl)meth-yl]sulfan-yl})methyl-idene)hydrazin-1-yl-idene]meth-yl]phenol: crystal structure, Hirshfeld surface analysis and computational study.

Project description:The complete mol-ecule of the title hydrazine carbodi-thio-ate derivative, C32H30N4O2S4, is generated by a crystallographic twofold axis that bis-ects the di-sulfide bond. The mol-ecule is twisted about this bond with the C-S-S-C torsion angle of 90.70?(8)° indicating an orthogonal relationship between the symmetry-related halves of the mol-ecule. The conformation about the imine bond [1.282?(2)?Å] is E and there is limited delocalization of ?-electron density over the CN2C residue as there is a twist about the N-N bond [C-N-N-C torsion angle = -166.57?(15)°]. An intra-molecular hydroxyl-O-H?N(imine) hydrogen bond closes an S(6) loop. In the crystal, methyl-ene-C-H??(tol-yl) contacts assemble mol-ecules into a supra-molecular layer propagating in the ab plane: the layers stack without directional inter-actions between them. The analysis of the calculated Hirshfeld surfaces confirm the importance of H?H contacts, which contribute 46.7% of all contacts followed by H?C/C?H contacts [25.5%] reflecting, in part, the C-H??(tol-yl) contacts. The calculation of the inter-action energies confirm the importance of the dispersion term and the influence of the stabilizing H?H contacts in the inter-layer region.

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].

In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, forming corrugated sheets lying parallel to (010).

Crystal structure of 2-((1E)-{2-[bis-(2-methyl-benzyl-sulfan-yl)methyl-idene]hydrazin-1-yl-idene}meth-yl)-6-meth-oxy-phenol.

Project description:In the title compound, C25H26N2O2S2, the central CN2S2 atoms are almost coplanar (r.m.s. deviation = 0.0058?Å). One phenyl ring clearly lies to one side of the central plane, while the other is oriented in the plane but splayed. Despite the different relative orientations, the phenyl rings form similar dihedral angles of 64.90?(3) and 70.06?(3)° with the central plane, and 63.28?(4)° with each other. The benzene ring is twisted with respect to the central plane, forming a dihedral angle of 13.17?(7)°. The S2C=N, N-N and N-N=C bond lengths of 1.2919?(19), 1.4037?(17) and 1.2892?(19)?Å, respectively, suggest limited conjugation over these atoms; the configuration about the N-N=C bond is E. An intra-molecular O-H?N hydrogen bond is noted. In the crystal, phen-yl-meth-oxy C-H?O and phen-yl-phenyl C-H?? inter-actions lead to supra-molecular double chains parallel to the b axis. These are connected into a layer via meth-yl-phenyl C-H?? inter-actions, and layers stack along the a axis, being connected by weak ?-? inter-actions between phenyl rings [inter-centroid distance = 3.9915?(9)?Å] so that a three-dimensional architecture ensues.
