(E)-4-(4-Hydr­oxy-3-nitro­benzyl­idene­amino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one

In the title compound, C(18)H(16)N(4)O(4), the dihedral angles between the central pyrazole ring and the pendant substituted and unsubstituted aromatic rings are 4.73 (12) and 44.24 (14)°, respectively. An intra­molecular O—H⋯O hydrogen bond occurs. In the crystal structure, an inter­molecular C—H⋯O...

Sumario:In the title compound, C(18)H(16)N(4)O(4), the dihedral angles between the central pyrazole ring and the pendant substituted and unsubstituted aromatic rings are 4.73 (12) and 44.24 (14)°, respectively. An intra­molecular O—H⋯O hydrogen bond occurs. In the crystal structure, an inter­molecular C—H⋯O inter­action may help to consolidate the packing and a short intra­molecular C—H⋯O contact also occurs.
