Crystal structure of (4Z)-4-[(2E)-1-hydroxy-3-(naphthalen-2-yl)prop-2-en-1-ylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
In the title compound, C23H18N2O2, the pyrazole ring subtends dihedral angles of 2.01 (13) and 1.55 (10)° with the pendant benzene ring and the naphthalene ring system, respectively. The mol-ecule is almost planar (r.m.s. deviation for the 27 non-H atoms = 0.025 Å) and intra-molecular O-H⋯O and C-H⋯O hydrogen bonds both close S(6) loops. In the crystal, very weak aromatic π-π stacking inter-act...
متن کامل(2Z)-3-(3-Bromoanilino)-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)but-2-en-1-one
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 i...
متن کامل(2E)-1-(4-Bromophenyl)-3-[3-(4-methoxyphenyl)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one
The pyrazole ring in the title compound, C25H19BrN2O2, is almost planar (r.m.s. deviation = 0.003 Å) and forms dihedral angles of 7.56 (13) and 56.48 (13)° with the N- and C-bound benzene rings, respectively. The prop-2-en-1-one residue has an E conformation about the C=C double bond [1.328 (4) Å] and is almost coplanar with the pyrazole ring [C-C-C-C torsion angle = -174.4 (3)°]. A twist betwe...
متن کامل(2Z)-1-(5-Hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3-(4-methylanilino)but-2-en-1-one
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.

In the title compound, C(24)H(15)Cl(2)N(3)O(3), the C=C double bond is E configured. The 1-phenyl-1H-pyrazole moiety is roughly planar (r.m.s. deviation of all fitted non-H atoms = 0.0780 Å), but the mean planes of the two components are inclined at an angle of 9.95 (7)°. The mean plane defined by the non-H atoms of the 1H-pyrazole ring encloses angles of 9.95 (7), 24.54 (6) and 43.02 (6)° with...
