Abstract

The synthesis and study of Co(III) dioximates containing [ZrF6]2- and [TiF6]2- anions, with general formula [Co(DioxH)2(L)2]2[MF6]·nH2O where DioxH-–dimethylglyoxime or 1,2-cyclohexanone dioxime monoanion and L–Thio (thiocarbamide), Py (pyridine), An (aniline) or SAM (sulfanilamide) have been performed. The composition and structures were established by elemental analysis, UV-Vis, IR and X-ray methods. The effect of some synthesized compounds on biomass accumulation by fungi Aspergillus niger 33 – producer of amylases was tested.
