(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 hy­droxy-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 ang...

Descripción
Sumario:In the title compound, C(20)H(18)BrN(3)O(2), the central carbonyl group forms amine-N—H⋯O and hy­droxy-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 bromo­benzene rings indicates an overall twist in the mol­ecule. In the crystal packing, mol­ecules assemble into dimeric aggregates via C—H⋯π inter­actions.
