New Schiff bases derived by the condensation of methyl, chloro, and bromo substituted 2' hydroxy propiophenones with aliphatic and aromatic amines have been synthesized. The Schiff bases are yellow solids with sharp melting points. Schiff bases The spectral characterization of these newly synthesized Schiff base ligands has been done.These Schiff bases were characterized by IR spectroscopy, Nuclear magnetic resonance spectroscopy, UV spectroscopy, and Mass spectroscopy. IR spectra confirmed the presence of the phenolic OH group and azomethine group.

Abstract Reactions of 2,4-dinitrophenylhydrazine with salicylaldehyde, pyridine-2-carbaldehyde and 2- aminobenzophenone in methanol result in the hydrazone Schiff base ligands salicylaldehyde-, pyridine- 2-carbaldehyde-, and 2-aminobenzophenone-2,4-dinitrophenylhydrazone, respectively. Crystals of salicylaldehyde-2,4-dinitrophenylhydrazone are monoclinic, space group P21/c, a = 13.820(3), b = 4.3515(9), c = 25.159(7) Å , β = 123.01(2)° with Z = 4. The molecular packing is mostly a zigzag or herring-bone pattern.
