Comparison of complex formation by thallium(I) and potassium salts of potentially chelating anions

Abstract

Potassium and thallium salts, K(L) and Tl(L), have been prepared from the following acids H(L) where (L) is a potentially bidentate ligand : 8-hydroxyquinoline, H(1), isonitrosoacetophenone, H(2), 1-nitroso-2-naphthol, H(3), 2-nitrophenol, H(4), 2-aminobenzoic acid, H(5), 2,4-dinitrophenol, H(6), 2-hydroxybenzoic acid, H(7), and 2-nitrobenzoic acid, H(8). The thallium compounds, except Tl(6) have low conductivities in N-methylpyrrolidone. Addition of acids H(L′) to the potassium salts K(L) gave the following new adducts K(6),H(7), K(3),2H(1), K(5),2H(1), K(6),2H(3), and K(8),2H(3). No corresponding thallium adducts Tl(L),H(L′) could be obtained.

With 2,2′-bipyridyl a 1 : 1 adduct was obtained only with Tl(6). On addition to the corresponding metal salts 1,10-phenanthroline, phen, yielded Tl(4),phen, Tl(5),phen, Tl(6),phen, Tl(7),phen, Tl(8),phen, and K(7),2phen,-2H2O. 2,9-Dimethyl-1,10-phenanthroline, dmphen, on addition to the metal salts, gave Tl(5),dmphen, Tl(6),dmphen, Tl(7),dmphen, Tl(8),dmphen, K(5),dmphen, and K(7),dmphen.
