The title compound, C 24 H 17 N 4 Cl, was synthesized by the reaction of 5-amino-3-methyl-1-phenylpyrazole with 3-(2chlorophenyl)-1-(2-pyridyl)prop-2-en-1-one in glycol under microwave irradition. X-ray crystal structure analysis reveals that the substituted pyridine ring is almost coplanar with the
The title compound, C 19 H 16 BrN 3 O, was synthesized by the reaction of 5-amino-3-methyl-1-phenylpyrazole with 4-bromophenylaldehyde and Medrum's acid in glycol under microwave irradiation. X-ray crystal structure analysis reveals three crystallographically independent molecules in the asymmetric
The geometrical parameters for the title compound, C 16 H 13 NO 2 S, are normal. The non-centrosymmetric crystal packing, which is consistent with the non-zero second harmonic generation response, may be influenced by a weak intermolecular C-HÁ Á ÁO interaction.
In the title compound, C~14~H~12~N~2~O~3~, the dihedral angle between the two aromatic rings is 86.13 (15)°. Intermolecular N—H...O hydrogen bonds [N...O = 2.886 (3) Å and N—H...O = 174 (3)°] between the NH~2~ and C=O groups link the molecules into a one-dimensional ribbon augmented by secondary N—H
The enone group and the benzene rings of the title compound, C 16 H 13 NO 4 , are each planar. In the crystal structure, intermolecular C-HÁ Á ÁO interactions form chains along the a axis.
