Abstract

Azo ligand 11-(4-methoxyphenyl azo)-6-oxo-5,6-dihydro-benzo[4,5] imidazo[1,2-c] quinazoline-9-carboixylic acid was derived from 4-methoxyaniline and 6-oxo-5,6-dihydro-benzo[4,5]imidazo[1,2-c]quinazoline-9-carboxylic acid. The presence of azo dye was identified by elemental analysis and spectroscopic methods (FT-IR and UV-Vis). The compounds formed have been identified by using atomic absorption in flame, FT.IR, UV-Vis spectrometry magnetic susceptibility and conductivity. In order to evaluate the antibacterial efficiency of ligand and its complexes used in this study three species of bacteria were also examined. Ligand and its complexes showed good bacterial efficiencies. From the obtained data, an octahedral geometry was proposed for all prepared complexes.

Highlights

Azo dyes which contain O, N-donor atoms react as chelating agents for many elements and present bioactive properties [1, 2]
These metal chelates were used for industrial applications, synthesis, leather dyeing, vinyl polymers, for pharmaceuticals, inhibition of DNA, RNA, protein synthesis, nitrogen fixation [7, 8]
In this work synthesis of azo dye by reaction of 4-methoxyaniline with 6-oxo-5,6-dihydrobenzo[4,5] imidazo[1,2-c]quinazoline-9-carboxylic acid, the metal chelates of azo dye have been produced and identified using different spectral analyses

Summary

Introduction

Azo dyes which contain O, N-donor atoms react as chelating agents for many elements and present bioactive properties [1, 2] Because of their low price and color fastness, the produced azo dyes have been investigated for industrial applications mainly, such as clothes, leather, plastics, food, cosmetics and toys [3, 4]. Metal chelates for heterocyclic azo compounds which were more interesting in inorganic and organometallic chemistry, and have been granted for application in bioactive systems, catalysis and materials science [6] These metal chelates were used for industrial applications, synthesis, leather dyeing, vinyl polymers, for pharmaceuticals, inhibition of DNA, RNA, protein synthesis, nitrogen fixation [7, 8]. In this work synthesis of azo dye by reaction of 4-methoxyaniline with 6-oxo-5,6-dihydrobenzo[4,5] imidazo[1,2-c]quinazoline-9-carboxylic acid, the metal chelates of azo dye have been produced and identified using different spectral analyses
