4-[(1-Hydroxy-2-naphthyl)methyleneamino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
The title anti-pyrine derivative, C(22)H(19)N(3)O(2), was synthesized by the reaction of 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one and 1-hy-droxy-naphthalene-2-carbaldehyde in methanol solution. As expected, the compound adopts a trans configuration about the central C=N bond. The N atom is involved in an intra-molecular O-H⋯N bond which stabilizes the mol-ecular configuration. In...

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...

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....

The asymmetric unit of the title compound, C11H12N2O·C25H28N4O2, contains two different mol-ecules. The smaller is known as anti-pyrine [systematic name: 1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one] and the larger is built up from two antypirine mol-ecules which are connected through a C atom of the pyrazolone ring to a central propanyl part [systematic name: 4,4'-(propane-2,2-di-yl)bis-[1,5-dim...
