Abstract

The transition metal complexes of hydrazones were synthesized by taking two metals, i.e., Cu (II) and Ni (II). The hydrazones
were prepared by the hydrazides of three acids, i.e., oxalic acid, malonic acid, and thiomalic acid reacting with the known amount
of different aldehydes. Fourier-transform infrared (FTIR) bands in the region of 380–370, 460–450, and 320–300 cm−1 confirm
the formation of metal complexes with hydrazones. Synthesized hydrazones and their metal complexes were characterized
through analytical techniques, i.e., FTIR, ultraviolet (UV)-visible, and elemental analysis, and the magnetic susceptibility was
calculated by Gouy’s method. The magnetic moment of copper complexes was 1.77–2.05 B.M. and for nickel complexes was
3.04–4.50 B.M. The metal complexes of hydrazones were gave encouraging results.
