(E)-4-(4-Hydr-oxy-3-nitro-benzyl-idene-amino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one.

ABSTRACT: 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 intra-molecular O-H?O hydrogen bond occurs. In the crystal structure, an inter-molecular C-H?O inter-action may help to consolidate the packing and a short intra-molecular C-H?O contact also occurs.

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 intra-molecular O-H⋯O hydrogen bond occurs. In the crystal structure, an inter-molecular C-H⋯O inter-action may help to consolidate the packing and a short intra-molecular C-H⋯O contact also occurs. ...[more]
