(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...

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.

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 ...

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-molecu...

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, ov...
