2-[(3,5-Dimethyl-1-phenyl-1H-pyrazol-4-yl)methylidene]indan-1,3-dione
In the title compound, C(21)H(16)N(2)O(2), the five-membered heterocyclic ring makes a dihedral angle of 47.06 (6)° with the attached benzene ring, whereas the indan-1,3-dione ring system and the benzene ring are oriented at a dihedral angle of 21.92 (7)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(22) loops. Aromatic π-π stacking inter-actions [c...

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 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...
