| Popis: | The thermal decomposition of the complexes Zn(form)2⋅2phen (I), Zn(ac)2⋅2phen (II), Zn(prop)2⋅2phen (III), Zn(but)2⋅2phen (IV), where phen=phenazone, form=formiate, ac=acetate, prop=propionate, but=butyrate has been studied in air by TG/DTG and DTA methods. The possible mechanism of the thermal decomposition was proposed. The final product of thermal decomposition was ZnO. IR data show unidentate coordination of carboxylate group to Zn(II) ion. The complexes were tested against various strains of microorganisms and their efficiency decrease in the sequence yeasts >bacteria>filamentous fungi. |
