(2E)-2-(2-Phenylhydrazin-1-ylidene)propanoic acid
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 ...

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 bo...
متن کامل(2E)-2-[(2E)-3-Phenylprop-2-en-1-ylidene]-2,3-dihydro-1H-inden-1-one
The title indan-1-one derivative, C(18)H(14)O, is planar with an r.m.s. deviation for all 19 non-H atoms of 0.098 Å. The conformation about each of the C=C bonds [1.343 (3) and 1.349 (3) Å] is E. Supra-molecular layers in the bc plane, mediated by C-H⋯O and π-π [ring centroid-centroid distance = 3.5282 (15) Å] inter-actions, feature in the crystal packing.

The title compound, C21H21NO, is a vinyl-ogous amide (enaminone) produced by reaction of 1-(2-phenyl-prop-2-en-1-yl)pyrrolidine-2-thione with phenacyl bromide. In the mol-ecule, the phenyl rings are twisted from the mean plane of the pyrrolidine ring by 11.2 (1) and 67.3 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules related by translation along the b axis into chains.

The asymmetric unit of the title compound, C(23)H(16)O(2), contains two independent mol-ecules in which the dihedral angles between the anthracene ring system and the benzene ring are 73.0 (3) and 73.3 (3)°. In both independent mol-ecules, the hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond. The crystal packing is stabilized by π-π inter-actions [centroid-centroid distances...
