4-(1,3-Benzothiazol-2-yl)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
The central five-membered ring of the title compound, C(18)H(15)N(3)OS, is almost planar (r.m.s. deviation = 0.028 Å) and the benzothia-zole fused-ring system is close to coplanar with this ring [dihedral angle = 6.1 (1)°]. The phenyl substituent is twisted by 62.5 (1)°.

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...

In the title compound, C(26)H(23)N(5)O(2)S, an intra-molecular N-H⋯O inter-action generates an S(6) ring. The essentially planar S(6) and pyrazole rings [maximum deviations = -0.0270 (14) and 0.0195 (15) Å, respectively] are nearly coplanar, making a dihedral angle of 3.94 (6)°. The S(6) ring makes dihedral angles of 23.79 (6), 78.53 (6) and 67.91 (6)° with the pyrazolone ring, the pyrazole rin...

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...
