A series of cobalt, nickel, copper, and zinc complexes of bidentate Schiff bases derived from the condensation reaction of 4-amino-5-mercapto-3-methyl/ethyl-1,2,4-triazole with 2,4-dichlorobenzaldehyde were synthesized and tested as antimicrobial agents. The synthesized Schiff bases and their metal complexes were characterized with the aid of elemental analyses, magnetic moment measurements, spectroscopic and thermogravimetric techniques. The presence of coordinated water in metal complexes was supported by infrared and thermal gravimetric studies. A square planar geometry was suggested for Cu(II) and octahedral geometry proposed for Co(II), Ni(II), and Zn(II) complexes. The Schiff bases and their metal complexes have been screened for antibacterial (Pseudomonas aeruginosa, Bacillus subtilis) and antifungal activities (Aspergillus niger, A. flavus). The metal complexes exhibited significantly enhanced antibacterial and antifungal activity as compared to their simple Schiff bases.

During researching the spectra of biocomplexes of synthesized metals synthesized by us with the organic laxand Naxogin (nimorazole), we compared the spectra of the obtained complexes with the ir-spectra of free (uncoordinated) naxogin (nimorazole). The research showed that the stretching vibration frequencies υ(C=N) were A~10–25 cm-1 in the high- frequency region and rarely in the higher metallicity (but in the acceptable range), which indicates that naxogin is present in these metal complexes (nimorazole). In a coordinated state through one of the two nitrogen atoms of the imidazole cycle. Comparisons were also made with the spectra of noxogenic (nimorazole) metal complexes (manganese, cobalt, nickel, copper, zinc) and other metals chromium(II), iron(II) and iron(III), which convinced us that organic ligands were only centrally connected with the complexes atoms.
