(2Z)-1-(5-Hy-droxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3-(4-methyl-anilino)-but-2-en-1-one.

ABSTRACT: A twist is evident in the title compound, C(21)H(21)N(3)O(2), the dihedral angle between the terminal six-membered rings being 29.46?(10)°; the linked five- and six-membered rings are coplanar [1.30?(11)°]. The carbonyl O atom accepts intra-molecular hydrogen bonds from the adjacent hy-droxy and amine groups. The three-dimensional crystal packing is achieved through C-H?? inter-actions.

A twist is evident in the title compound, C(21)H(21)N(3)O(2), the dihedral angle between the terminal six-membered rings being 29.46 (10)°; the linked five- and six-membered rings are coplanar [1.30 (11)°]. The carbonyl O atom accepts intra-molecular hydrogen bonds from the adjacent hy-droxy and amine groups. The three-dimensional crystal packing is achieved through C-H⋯π inter-actions. ...[more]

(2Z)-3-(4-Fluoro-anilino)-1-(5-hy-droxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)but-2-en-1-one.

Project description:The central carbonyl group in the title compound, C(20)H(18)FN(3)O(2), forms amine-hy-droxy N-H?O and hy-droxy-hy-droxy O-H?O hydrogen bonds, leading to two S(6) rings. The N-bound phenyl ring is coplanar with the five-membered ring to which it is attached [dihedral angle = 6.27?(10)°], but an overall twist in the mol-ecule is evident, the dihedral angle between the terminal phenyl and benzene rings being 27.30?(10)°. Mol-ecules aggregate into a three-dimensional architecture via C-H?F, C-H?O and C-H?? inter-actions.

(2Z)-3-(4-Chloro-anilino)-1-(5-hy-droxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)but-2-en-1-one.

Project description:With the exception of the terminal benzene rings, the atoms in the title compound, C(20)H(18)ClN(3)O(2), are approximately coplanar (r.m.s. deviation = 0.0495?Å). The benzene/chloro-benzene rings form dihedral angles of 3.02?(4) and 41.59?(5)°, respectively, with this plane. The hy-droxy, amino and carbonyl groups all lie to the same side of the mol-ecule, enabling the formation of intra-molecular O-H?O and N-H?O hydrogen bonds that close S(6) rings. The configuration about the 2-butene bond is Z. Supra-molecular chains mediated by C-H?Cl inter-actions and aligned along the c axis are found in the crystal packing. These assemble into layers that are connected by weak ?-? inter-actions between centrosymmetrically related chloro-benzene rings [3.8156?(9)?Å].

(2Z)-1-(5-Hy-droxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3-(4-meth-oxy-anilino)but-2-en-1-one.

Project description:The central residue in the title compound, C(21)H(21)N(3)O(3), is close to planar (r.m.s. deviation = 0.0753?Å for all non-H atoms from OH to NH inclusive): the hy-droxy, amino and carbonyl groups all lie to the same side of the mol-ecule (the conformation about the ethene bond is Z), facilitating the formation of intra-molecular O-H?O and N-H?O hydrogen bonds that close S(6) rings. However, overall the mol-ecule is twisted as the terminal aromatic rings are not coplanar with the central plane [dihedral angles = 20.55?(5) and 80.90?(4)° for the N-bound phenyl ring and the meth-oxy-benzene ring, respectively]. The dihedral angle between the rings is 82.14?(7)°. Supra-molecular layers in the ac plane mediated by C-H?? inter-actions are found in the crystal.

(2Z)-3-(3-Bromo-anilino)-1-(5-hy-droxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)but-2-en-1-one.

Project description:In the title compound, C(20)H(18)BrN(3)O(2), the central carbonyl group forms amine-N-H?O and hy-droxy-O-H?O hydrogen bonds, which lead to two fused S(6) rings. The N-bound phenyl ring is coplanar with the five-membered ring to which it is attached [dihedral angle = 5.22?(18)°], but the dihedral angle [33.87?(17)°] between the terminal phenyl and bromo-benzene rings indicates an overall twist in the mol-ecule. In the crystal packing, mol-ecules assemble into dimeric aggregates via C-H?? inter-actions.

4-[(3-Hy-droxy-anil-ino)-(phenyl)-methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

Project description:In the title compound, C(23)H(19)N(3)O(2), the dihedral angles formed by the pyrazolone ring with the three benzene rings are 30.91?(6), 60.96?(4) and 57.01?(4)°. The ligand is in the enamine-keto form and its structure is stabilized by an intra-molecular N-H?O hydrogen bond. In the crystal, O-H?N hydrogen bonds link mol-ecules into chains parallel to [01-1].

1-[(4-Hy-droxy-anilino)methyl-idene]naphthalen-2(1H)-one.

Project description:The title Schiff base, C17H13NO2, crystallizes in the zwitterionic form and an N-H⋯O hydrogen bond closes an S(6) ring. The dihedral angle between the aromatic ring systems is 15.62 (9)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into C(11) chains propagating in [010].

4-Hy-droxy-1-methyl-3-phenyl-quinolin-2(1H)-one.

Project description:In the title compound, C(16)H(13)NO(2), the quinoline system is approximately planar with a maximum deviation from the least-squares plane of 0.059?(1)?Å for the N atom. The phenyl ring is rotated by 62.16?(4)° with respect to the plane of the quinoline system. In the crystal, O-H?O hydrogen bonds link mol-ecules into infinite chains running along the b-axis direction.

4-[(1-Hy-droxy-2-naphth-yl)methyl-ene-amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one.

Project description:The title anti-pyrine derivative, C(22)H(19)N(3)O(2), was synthesized by the reaction of 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one and 1-hy-droxy-naphthalene-2-carbaldehyde in methanol solution. As expected, the compound adopts a trans configuration about the central C=N bond. The N atom is involved in an intra-molecular O-H?N bond which stabilizes the mol-ecular configuration. In the crystal structure, adjacent mol-ecules stack with no short contacts.

Project description:In the title compound C(14)H(17)N(3)O(2), the dihedral angle between the rings is 16.68 (13)°. Although the compound crystallizes in the keto form, the possibility of keto-enamine-enol-imine tautomerism is explained by a strong intra-molecular N-H⋯O hydrogen bond.

(Z)-4-[(2-Amino-4,5-dichloro-anilino)(phenyl)methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

Project description:The mol-ecule of the title compound, C(23)H(18)Cl(2)N(4)O, assumes a non-planar conformation in which the pyrazolone ring forms dihedral angles of 32.61?(19), 76.73?(14) and 52.57?(19)° with the three benzene rings. The secondary amino group is involved in an intra-molecular N-H?O hydrogen bond. In the crystal, mol-ecules are linked by pairs of N-H?O hydrogen bonds, forming inversion dimers. An offset stacking inter-action is observed between the chloro-substituted benzene rings protruding on both sides of these dimers [centroid-centroid distance = 3.862?(1)?Å].
