4-[(Anthracen-9-ylmethylidene)amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
In the title compound, C(26)H(21)N(3)O, the phenyl ring of the 4-amino-anti-pyrine group and the heterocyclic five-membered ring along with its substituents, except for the N-bound methyl group (r.m.s. deviation = 0.0027 Å), form a dihedral angle of 54.20 (5)°. Two S(6) ring motifs are formed due to intra-molecular C-H⋯N and C-H⋯O hydrogen bonds. In the crystal, mol-ecules are linked into supra...

In the title compound, C(23)H(22)N(4)O, the pyrazole ring makes dihedral angles of 45.57 (11)° with the attached phenyl ring, and 83.98 (10) and 67.85 (10) °, respectively, with the other phenyl ring and the pyridyl ring. The pyridyl ring makes a dihedral angle of 80.15 (10)° with the adjacent phenyl ring. In the crystal, N-H⋯O hydrogen bonds supplemented by weak C-H⋯O hydrogen bonds link the m...
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 ...
