In this study, Fe(II) (2) {[Fe(1)2]}, Co(II) (3) {[Co(1)2].3H2O}, Ni(II) (4) {[Ni(1)2].3H2O}, Cu(II) (5) {[Cu(1)2]} and Zn(II) (6) {[Zn(1)2].3H2O} complexes of (E)-4-oxo-4-(4-sulfamoylanilino)but-2-enoic acid (1) were synthesized and their structures were suggested by AAS, IR, UV-vis, magnetic moment and molar conductivity measurements. In addition, compounds 1-6 of antimicrobial activities against Bacillus subtilis, Listeria monocytogenes (ATCC 7644), Enterococcus faecalis (ATCC 29212), Staphylococcus aureus (NRRL-B 767) (Gram positive), Pseudomonas aeruginosa (ATCC 27853) and Escherichia coli (ATCC 25922) (Gram negative) (bacteria) and Candida Albicans (ATCC 14053) (yeast) were tested using the microdilution method. Antifungal activity results were compared with the control compound Fluconazole, while antibacterial results were compared with Levofloxacin, Cefepime and Vancomycin. As a result of the activity studies, it was observed that the newly synthesized compounds had antimicrobial activity against bacteria and yeasts. In the activity results of the compounds, 1-6 in B. subtilis bacteria, 2-6 in E. faecalis bacteria, 1-6 in S. aureus bacteria, 4 and 5 in E. coli bacteria, 1, 3, 5 and 6 in L. monocytogens bacteria, 1, 3 and 5 in P. aeruginoa bacteria and 2-4 in C. albicans yeast were observed.
