The ligand and their metal complexes were screened for their antimicrobial activities by the agar-well diffusion technique using DMSO as a solvent against the following bacterial species: <i>Bacillus subtilis</i>, <i>Staphylococcus aureus</i>, <i>Escherichia coli</i> and <i>Pseudomonas aeruginosa</i> and antifungal activity against <i>Aspergillus niger</i>, <i>Aspergillus flavus</i>, <i>Saccharomyces cerevisiae</i> and <i>Candida albicans</i>. The obtained results were compared with some types of known antibiotics. The minimum inhibitory concentration (MIC) values were calculated at 30 °C for 24−48 h. The activity data show that the complexes are more potent antimicrobials than the parent ligand.http://ajol.info/index.php/bcse/article/view/63364Nitrilotriacetic acidMetal complexesIR<sup>1</sup>H-NMR SpectroscopyThermal analysisAntimicrobial activity
