Synthesis, spectral and antibacterial study of azo compound derived from (3,3΄-dimethyl-biphenyl-4,4΄-diamine)‎ and its metal complexes

Abstract EN

The present study includes synthesis of azo compound 4,4΄-Bis (resorcinolazo) - 3,3΄-Dimethyl-biphenyl [BRADB], the azo compound ligand was prepared from reaction 3,3΄-Dimethyl-biphenyl-4,4΄-diamine with conc.HCl and NaNO2 then with resorcinol.

The metal complexes were prepared by reaction of some transition metals with the above ligand in ethanol.

The prepared compounds were characterized by (infrared and electronic spectral measurements) and conductivity measurement.

From the molar ratio method, the stoichiometry of the prepared complexes was found to be 2 : 1 (metal : ligand).

The molar conductance data revealed that all the metal chelates were non-electrolytes.

The spectral studies showed the geometry around Fe ion is distorted octahedral, while the geometry around Zr and V ions are square-pyramidal.

The azo compound ligand and the metal chelats were studied for antibacterial activities against (Enterococcus and Staphylococcus epidermidis) are Gram positive and (Salmonella and Proteus) are Gram negative.

The azo compound ligand and its chelats were exhibited a variable activity of inhibition on the growth of the bacteria.
