The heterocyclic compound was ground with metal (III) carbonates to create the appropriate complexes of Cr. Elemental, melting/decomposition temperature estimation, conductivity and infrared spectroscopy tests were used to characterize the produced chemical. The ligand's infrared spectroscopic investigation reveals peaks at 1674cm-1, which demonstrate the existence of azomethane in guanine, and 1592cm-1, which confirm the presence of azomethane in benzoguanamine, which confirms the creation of a bond between an azo group and a metal, respectively. Guanine with melting point of about 3600C suggests that it is stable at high temperatures, but the breakdown temperature of the Cr complex over 3600C indicates that the complex is extremely stable. The breakdown temperature of the Cr complex, which is about 2700C, suggests that the complex is relatively stable at high temperatures. In contrast, the melting point temperature of the benzoguanamine ligand, which is 2280C, shows that it is relatively stable at high temperatures. When the conductivity of complexes is compared to theoretical values, they are not electrolytic. At greater concentrations (1000 ?g/disc and 500 ?g/disc), some bacteria and fungus were resistant to the ligand and its associated complexes, but other organisms showed no response to any concentration. However, research on the anti-oxidant effect of Cr complex revealed that all species were considerably impacted, even at low concentrations (250 ?g/disc). | | Keywords : | | | anti-microbial activities, an-oxidant guanine, benzoguanamine, Cr (III), solvent free synthesis. |
