Multinuclear n.m.r. spectroscopy of [NEt4][SbXnF6 –n], X Br or Cl, and [NEt4][AsClnF6 –n] in solution in MeCN

Abstract

The anions in the title, n 1–6, have been conclusively characterised in solution by ¹⁹F, ⁷⁵As, and ¹²¹Sb n.m.r. spectroscopy and, for n 1–5, shown to be stable with respect to fluorine redistribution reactions.
