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. |
