ULTRASONIC SPEED AND ACOUSTICAL PARAMETERS OF SOME SYNTHESIZED 3D METAL COMPLEXES IN SOLUTION AT 301K

Ultrasonic propagation parameters yield valuable information regarding the behavior of liquid systems, because intramolecular association, dipolar interactions, complex formation and related stuructural changes effect the compressibility of the system which in turn produces corresponding variations in the ultrasonic velocity. Some metal complexes of Co (II), Ni(II) and Cu(II) derived from 2-acetonaphthone with 2-amino-4-methylbenzothiazole (AABT), 2-amino-4-chlorophenol (AACP) and 2-aminothiazole (ACAT) have been synthesized and their ultrasonic velocity and density have been measured in non- aqueous solution methanol at 301.15K. The value of apparent molar volume, acoustic impedance, adiabatic compressibility, inter molecular free length, molar sound velocity (Rao’s constant), free volume, internal pressure and cohesive forces have been calculated from density and ultrasonic velocity data. The results have been discussed in the light of solvent interaction and structure effecting metal complexes. Keywords- Ultrasonic velocity, Density, Acoustical parameters and Metal complexes
