摘要：As a result of cobalt (III) β-aminoethylate protonation reactions with sulfuric and nitric acids, several new coordinationcompounds of composition [Co(Hetm)3](NO3)3 (1) and [Co(Hetm)3]2(SO4)3⋅4H2O (2) have been synthesized. The reactionbetween β-aminoethanol and cobalt(III) nitrate, acetate and sulfate in neutral or slightly basic alcoholic media leads tothe formation of cobalt (III) coordination compounds, which internal sphere includes both molecules of neutral β-aminoethanol(Hetm) and ions of its deprotonated form (etm). The general formula of the complexes can be given as[Co(Hetm)3][Co(etm)3]X3⋅nH2O, where X = NO3- (3), CH3COO- (4), 1/2SO42- (5); n = 0, 7, or 3 correspondingly. Thebiologic activity study of the synthesized complexes revealed that the algae biomass obtained in the nutritive media,containing coordination compounds, depends on the internal coordination sphere of the cobalt compound
