Abstrakt: 1.When the donor oxygen atoms of acetylacetonate are replaced by sulfur atoms, the acceptor capacity of the corresponding internal complex compounds of nickel is reduced, and the tendency for a decrease in the acceptor properties increases with the accumulation of sulfur atoms in the ligand.2.A comparative spectrophotometric investigation of the state of the internal coordination sphere of the nickel ion in nonaqueous solutions of Ni(AA)2 · (H2O)2 and Ni(DTAA)2 in the interaction with electron donor reagents made it possible to arrange the reagents in a series with respect to increase in their axial perturbation of the coordination sphere: dimethyl sulfoxide < tri-n-octylamine < methanol < pyridine < tri-n-octylphosphine oxide.
