Abstract: New fluorine-containing cobalt(III) dioximates [Co(DmgH) 2 (Thio) 2 ] 2 F[PF 6 ] (I) and [Co(DmgH) 2 (Sam) 2 ] 2 [TiF 6 ] · 4H 2 O (II) (DmgH = dimethylglyoxime monoanion, Thio = thiourea, Sam = sulfanilamide) were obtained. The structure of I was determined by X-ray diffraction (CIF file CCDC no. 1852216). The crystals are cubic, space group (Formula Presented.). The octahedral coordination polyhedron of the metal is formed by the N 4 S 2 set of donor atoms of two DmgH¯ ligands and two Thio molecules. The effect of compounds I and II and two previously described compounds of this class with fluorine anions, [Co(DmgH) 2 (Thio) 2 ] 2 [TiF 6 ] · 2H 2 O (III) and [Co(DmgH) 2 (An) 2 ] 2 [ZrF 6 ] (IV) (An = aniline), on the physiological processes of the red microalga Porphyridium cruentum was studied. Complex III in concentration of 20 mg/L increased the microalga productivity by 20% and lipid biosynthesis by 17% and can be proposed for biotechnology applications.
