4-{[(E)-(3,5-Dimethyl-1-phenyl-1H-pyrazol-4-yl)methylidene]amino}-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
The title Schiff base compound, C(23)H(23)N(5)O, was synthesized by the reaction of 4-amino-phenazone and 3,5-dimethyl-1-phenyl-pyrazole-4-carbaxaldehyde. The mol-ecule adopts an E configuration about the central C=N double bond. A weak intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The dihedral angle between the pyrazole rings is 24.72 (10)° and the dihedral angles between t...

The title Schiff base compound, C(22)H(24)IN(3)O(2), adopts an E configuration about the central C=N bond. The pyrazolone ring makes a dihedral angle of 49.68 (10)° with its attached phenyl ring. The phenolate plane makes dihedral angles of 16.78 (9) and 50.54 (9)°, respectively, with the pyrazolone ring and the terminal phenyl ring. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring...

In the title compound, C(22)H(26)N(4)O(2), the phenyl ring and hy-droxy-benzene group are twisted with respect to the central pyrazolone ring, making dihedral angles of 54.05 (5) and 21.80 (6)°, respectively. One of the ethyl groups is disordered over two positions with site occupancies of 0.872 (6) and 0.128 (6). The mol-ecular structure features short intra-molecular O-H⋯N and C-H⋯O contacts....
متن کامل(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 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 ...
