6-[(2,4-Di-methyl-anilino)methyl-idene]-2-hy-droxy-cyclo-hexa-2,4-dienone.

ABSTRACT: In the title compound, C15H15NO2, the dihedral angle between the aromatic rings is 5.86?(6)°, and an intra-molecular N-H?O hydrogen bond generates an S(6) motif, which helps to stabilize the enamine-keto tautomer. An intra-molecular O-H?O hydrogen bond also occurs. In the crystal, inversion dimers linked by pairs of O-H?O hydrogen bonds generate R 2 (2)(10) loops. A C-H?O inter-action links the dimers into [010] chains and aromatic ?-? stacking [centroid-centroid separation = 3.6131?(9)?Å] also occurs.

In the title compound, C15H15NO2, the dihedral angle between the aromatic rings is 5.86 (6)°, and an intra-molecular N-H⋯O hydrogen bond generates an S(6) motif, which helps to stabilize the enamine-keto tautomer. An intra-molecular O-H⋯O hydrogen bond also occurs. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(10) loops. A C-H⋯O inter-action links the dimers into [010] chains and aromatic π-π stacking [centroid-centroid separation = 3.6131 (9) Å] also ...[more]

Crystal structure and Hirshfeld surface analysis of (<i>Z</i>)-6-[(2-hy-droxy-4-methyl-anilino)-methyl-idene]-4-methyl-cyclo-hexa-2,4-dien-1-one.

Project description:The title compound, C15H15NO2, is a Schiff base that exists in the keto-enamine tautomeric form and adopts a Z configuration. The mol-ecule is almost planar, with the two phenyl rings twisted relative to each other by 9.60 (18)°. There is an intra-molecular N-H⋯O hydrogen bond present forming an S(6) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds link adjacent mol-ecules into inversion dimers with an R 2 2(18) ring motif. The dimers are linked by very weak π-π inter-actions, forming layers parallel to (01). Hirshfeld surface analysis, two-dimensional fingerprint plots and the mol-ecular electrostatic potential surfaces were used to analyse the inter-molecular inter-actions, indicating that the most important contributions for the crystal packing are from H⋯H (55.2%), C⋯H/H⋯C (22.3%) and O⋯H/H⋯O (13.6%) inter-actions.

Crystal structure and Hirshfeld surface analysis of (<i>Z</i>)-6-[(2-hy-droxy-5-nitro-anilino)methyl-idene]-4-methyl-cyclo-hexa-2,4-dien-1-one.

Project description:The title compound, C14H12N2O4, is a Schiff base that exists in the keto-enamine tautomeric form and adopts a Z configuration. The mol-ecule is almost planar, the rings making a dihedral angle of 4.99 (7)°. The mol-ecular structure is stabilized by an intra-molecular N-H⋯O hydrogen bond forming an S(6) ring motif. In the crystal, inversion-related mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming dimers with an R 2 2(18) ring motif. The dimers are linked by pairs of C-H⋯O contacts with an R 2 2(10) ring motif, forming ribbons extended along the [20] direction. Hirshfeld surface analysis, two-dimensional fingerprint plots and the mol-ecular electrostatic potential surfaces were used to analyse the inter-molecular inter-actions present in the crystal, indicating that the most important contributions for the crystal packing are from H⋯H (33.9%), O⋯H/H⋯O (29.8%) and C⋯H/H⋯C (17.3%) inter-actions.

(Z)-6-[(5-Chloro-2-hydroxy-anilino)-methyl-ene]-4-methoxy-cyclo-hexa-2,4-dienone 0.25-hydrate.

Project description:The title compound, C(14)H(12)ClNO(3)·0.25H(2)O, exists in the keto-amine form, and the aromatic rings are oriented at a dihedral angle of 7.24 (7)°. Bifurcated intra-molecular N-H⋯(O,O) hydrogen bonds result in the formation of planar six- and five-membered rings. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains. π-π contacts between benzene rings [centroid-centroid distance = 3.5065 (9) Å] may further stabilize the structure.

Crystal structure of 2-(2,3-di-methyl-anilino)-N'-[(1E)-2-hy-droxy-benzyl-idene]benzohydrazide.

Project description:The asymmetric unit of the title compound, C22H21N3O2, consists of two independent mol-ecules (A and B) having differing conformations. The differences mainly concern the dihedral angles which the hy-droxy-phenyl and di-methyl-phenyl rings subtend to the central phenyl-ene ring, these being 30.16 (6) and 58.60 (6)° in mol-ecule A and 13.42 (7) and 60.31 (7)° in B. With the exception of the dimethyphenyl substituent, the conformations of the rest of each mol-ecule are largely determined by intra-molecular O-H⋯N and N-H⋯O hydrogen bonds. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains extending parallel to the a axis in which the types of mol-ecules alternate in an …A…B…A…B… fashion.

3-[1-(2-Hy-droxy-anilino)ethyl-idene]-3H-chromen-2,4-dione.

Project description:The title compound is a new amino-coumarin derivative, C17H13NO4, and was synthesized by the condensation of 2-amino-phenol and 3-acetyl-4-hy-droxy-coumarin. An intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. In the crystal, the molecules are linked into chains extending in the [010] direction by O-H?O hydrogen bonds. There is also a ?-? stacking inter-action between the bicyclic coumarin fragment and the phenol ring [centroid-centroid distance = 3.7510?(14)?Å], and these ring systems form between them a dihedral angle of 53.3?(2)°. Intermolecular hydrogen bond C-H?O hydrogen bonding is also observed in the interconnection of the crystal packing.
