Abstract
The electronic spectra of solutions of nickel 8-hydroxyquinolinate and 8-mercaptoquinolinate were investigated in benzene, benzene solutions of pyridine (Py), and dimethyl sulfoxide (DMSO), Py, and DMSO. The tendency for the formation of adducts with Py and DMSO is higher in the case of the hydroxyquinolinate than for the thiohydroxyquinolinate. The strength of the bond of nickel to the planar ligands depends on the nature of the donor atoms of the chelating reagents, and in the investigated internal complex compounds of nickel increases from O,N- to S,N-containing complexes. Pyridine is a more active donor reagent than DMSO in the systems studied.
