It was elaborated the methodology of synthesizing a series of new dioximates of Co(III) with the
general formula [Co(DioxH)2(L)2]X⋅nH2O, where DioxH – the dioxime anione: dimethylglyoxime (DH2),
1,2-cyclohexanedionedioxime (NioxH2); L - thiocarbamide (Thio), pyridine (Py), aniline (An), sulphanilamide (Sam);
X - [BF4]-, [ZrF6]2-, [TiF6]2-, whose structures have been studied with the help of contemporary physical methods:
spectroscopy IR, UV-Vis, RMN 1H, 19F, X-ray analysis. There were elaborated optimal conditions of using cobalt
dioximates with fl uorine in order to intensify the biosynthesis of amylases and lipases by Aspergillus and Rhizopus
strains, respectively. The tested compounds increase the lipolytic activity of Rhizopus arrhisus micromycetes.
