2-{(E)-1-[2-(2-Nitro-phen-yl)hydrazin-1-yl-idene]eth-yl}benzene-1,3-diol mono-hydrate.

ABSTRACT: The hydrazone mol-ecule in title monohydrate, C(14)H(13)N(3)O(4)·H(2)O, is almost coplanar, the dihedral angle between the terminal benzene rings being 3.22?(15)°; the nitro group is coplanar with the benzene ring to which it is bonded [O-N-C-C = -2.8?(4)°]. The hy-droxy group forms an intra-molecular hydrogen bond with the imine N atom, and the conformation about the imine bond [1.305?(3)?Å] is E. In the crystal, supra-molecular layers in the (203) plane are connected into a double layer via water-nitro O-H?O hydrogen bonds, along with ?-? inter-actions [ring centroid-centroid distance = 3.7859?(19)?Å].

Crystal structure and Hirshfeld surface analysis of dimethyl 5-[2-(2,4,6-trioxo-1,3-diazinan-5-yl-idene)hydrazin-1-yl]benzene-1,3-di-carboxyl-ate 0.224-hydrate.

Project description:In the crystal, the whole mol-ecule of the title compound, C14H12N4O7·0.224H2O, is nearly planar with a maximum deviation from the least-squares plane of 0.352 (1) Å. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring motif. In the crystal, mol-ecules are linked by centrosymmetric pairs of N-H⋯O hydrogen bonds, forming ribbons along the c-axis direction. These ribbons connected by van der Waals contacts, forming sheets parallel to the ac plane. There are also inter-molecular van der Waals contacts and and C-H⋯π inter-actions between the sheets. A Hirshfeld surface analysis indicates that the most prevalent inter-actions are O⋯H/H⋯O (41.2%), H⋯H (19.2%), C⋯H/H⋯C (12.2%) and C⋯O/ O⋯C (8.4%).

Project description:In the anion of the title hydrated salt, C2H10N22+·C21H13N3O8S2-·2H2O, the planes of the phenyl rings and the benzene ring of the 5-nitro-2-oxido-benzene-sulfonate group are inclined to one another by 44.42?(11), 56.87?(11) and 77.70?(12)°. In the crystal, the anions are linked to the cations and the water mol-ecules by N-H?O and O-H?O hydrogen bonds, forming a three-dimensional network. Furthermore, there are face-to-face ?-? stacking inter-actions between the centroids of one phenyl ring and the benzene ring of the 5-nitro-2-oxido-benzene-sulfonate group [centroid-centroid distance = 3.8382?(13)?Å and slippage = 1.841?Å]. A Hirshfeld surface analysis was conducted to verify the contributions of the different inter-molecular inter-actions.

Project description:In the title compound, C22H19N4S(+)·Br(-)·H2O, the dihedral angles between the phenyl groups and the mean plane of the thia-zolyl-idene ring are 34.69 (13) and 64.27 (13)°, respectively, while that between the thia-zolyl-idene and pyridinium rings is 14.73 (13)°. In the crystal, zigzag chains of alternating bromide ions and water mol-ecules associate through O-H⋯Br inter-actions run in channels approximately parallel to the b axis. These chains help form parallel chains of cations through N-H⋯O, C-H⋯N and C-H⋯Br hydrogen bonds.

4-{2-[(E)-Cyclo-pentyl-idene]hydrazin-1-yl}benzene-sulfonamide.

Project description:The title mol-ecule, C(11)H(15)N(3)O(2)S, features a five-membered ring which is twisted about the middle CH(2)-CH(2) bond. The benzene ring is inclined with respect to the imine residue [C-N-N-C torsion angle = 165.4?(2)°]. Supra-molecular layers in the bc plane are formed by hydrogen bonds between the amine H atoms and sulfonamide O and imine N atoms, as well as by a weak hydrazine H-atom inter-molecular inter-action with the second sulfonamide O atom.

N'-[(Z)-4-(Dimethyl-amino)benzyl-idene]-4-nitro-benzohydrazide mono-hydrate.

Project description:In the asymmetric unit of the title compound, C(16)H(16)N(4)O(3)·H(2)O, there are two symmetry-independent hydrazide mol-ecules with almost identical geometries, and two independent water mol-ecules. The dihedral angles between the two benzene rings in the two hydrazide mol-ecules are 0.11?(5) and 0.77?(5)°. In one mol-ecule, an intra-molecular C-H?O hydrogen bond generates a ring of graph-set motif S(5). Inter-molecular N-H?O, O-H?O, O-H?N and C-H?O hydrogen bonds and ?-? stacking inter-actions between the benzene rings [centroid-centroid distances in the range 3.5021?(6)-3.6403?(6)?Å] are observed, together with O?O [2.7226?(11)?Å], O?N [2.7072?(10)?Å] and N?O [2.7072?(10)-2.8582?(12)?Å] short contacts. The hydrazine mol-ecules are stacked along the b axis and adjacent mol-ecules are linked by water mol-ecules.

1,3-Bis[(-)-(S)-(1-phenyl-eth-yl)imino-meth-yl]benzene.

Project description:The title compound, C(24)H(24)N(2), is an enanti-omerically pure bis-aldimine, which displays twofold crystallographic symmetry, with two C atoms of the central benzene ring lying on the symmetry axis. The imine group is slightly twisted from the benzene core, with a dihedral angle of 12.72 (16)° between the benzene ring and the C=N-C(*) plane. The terminal phenyl rings make an angle of 66.44 (4)° and are oriented in opposite directions with respect to the benzene ring. In the crystal, mol-ecules inter-act weakly through a C-H⋯π inter-action involving the phenyl rings, and form chains along the 2(1) screw-axis in the [100] direction.

(3Z)-3-[(Z)-2-(2-Oxoindolin-3-yl-idene)hydrazin-1-yl-idene]indolin-2-one 0.17-hydrate.

Project description:In the title compound, C16H10N4O2·0.17H2O, prepared by the one-step condensation reaction of isatin with hydrazine hydrate under microwave irradiation, the complete organic mol-ecule is generated by crystallographic inversion symmetry and therefore exists in an S-trans conformation. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds, generating a three-dimensional framework with [001] channels, which are occupied by the disordered water mol-ecules.
