4-[(9-Ethyl-9H-carbazol-3-yl)methylideneamino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
The imino-carbon double bond in the title Schiff base, C(26)H(24)N(4)O, has an E configuration. The 13-membered carbazolyl fused-ring (r.m.s. deviation = 0.056 Å) is nearly coplanar with five-membered pyrazole ring (r.m.s. deviation = 0.036 Å) [dihedral angle between the two systems = 10.4 (1)°]; the phenyl substituent is twisted by 51.1 (1)° with respect to the five-membered ring.

In the title compound, C(28)H(30)N(2)O(2), the cyclo-hexene ring system adopts a sofa conformation. The crystal structure is stabilized by C-H⋯O inter-actions between methyl H atoms of the ethyl substituents and the O atoms of carbonyl groups of adjacent mol-ecules, and by an inter-molecular carbon-yl-carbonyl inter-actions [3.207 (2) Å].

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...

The asymmetric unit of the title compound, C(11)H(12)N(2)O, consists of two crystallographically independent mol-ecules (A and B) with similar geometries. Both mol-ecules exist in a keto form, the C=O bond length being 1.286 (2) Å in A and 1.283 (2) Å in B. The dihedral angles between the pyrazole ring and the attached phenyl ring are 43.28 (12) and 46.88 (11)°, respectively, for A and B. The e...

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...
