Abstract: Interaction of 2-propyl-8-mercaptoquinoline with Cu(II), Ag(I), Zn(II), Cd(II), Hg(II), Ga(III), In(III), T1(I), Pb(II), Sb(III), Bi(III), Fe(II), Co(II), Ni(II), Pd(II), Pt(II), Ru(III), Rh(III), and Os(III) ions in the system chloro­ form—water has been investigated. Absorption spectra have been studied, pH intervals of extraction of the complexes, their composition in extracts, their solubility in chloroform and stability in the two-phase system chloroform—wa­ ter have been determined. The difference in the properties of 2-propyl-8-mer- captoquinolinates in comparison to complexes of other alkyl derivatives is explained by steric hindrance in the molecules of complexes executed by the propyl group in the position 2 of the ligand.
