Preparation of metal organic compounds containing Schiff bases and study some of its mechanical properties

الملخص EN

This research included preparation of complexes for Ni ion chloride(II) Cr ion chloride(III) and aqueous iron chloride (III) with Schiff bases ligand (N, N) di methyl of the amino Benzaldhyde.

the prepared complexes were characterized by IR, UV and visible spectra.

Also the mechanical properties by technique of ultrasonic waves velocity at 40 KHz frequency were studied include the ultrasonic waves velocity, absorption coefficient of ultrasonic waves, relaxation time, relaxation amplitude, specific acoustic impedance compressibility, and bulk modules.

the results showed that all properties decrease with increase the ultrasonic waves velocity except the specific acoustic impedance and bulk modules which directly proportional to the velocity and all the results were compared with with those for similar compounds.
