Spectroscopic studies of inorganic fluoro-complexes. Part III. Fluorine-19 nuclear magnetic resonance studies of silicon(IV), germanium(IV), and titanium(IV) fluoro-complexes

Abstract

Anions of the type MF_6–2x B_x^2–(M = Si^IV, Ge^IV, or Ti^IV; B = bidentate-ligand) have been characterised in solution by ¹⁹F n.m.r. spectroscopy. For Ge^IV and Ti^IV, anions of the type MF₅OR^2– and MF₅O₂CR^2– have also been observed. Redistribution reactions of M(ox)₃^2– and MF₆^2– have been studied quantitatively (M = Si^IV, Ge^IV, Sn^IV, and Ti^IV).
