1H NMR Spectra of Phenylthallium (III) Crown-Ether Complexes, [C6H5Tl (III)(Crown)X]n(ClO4) (n=1 OR 2); Trans Influence of The X Groups

Abstract

Trans influence of the X groups on the spin-pin coupling constants between the thallium nucleus and the meta protons of the phenyl group attached to the thallium atom, J(Tl-H^m), were studied for a number of phenylthallium (III) crown-ether complexes, C₆H₅Tl (III) (crown)X]n(ClO₄) (n=1 or 2).
