Restricting Magnetic Interaction Pathways in Polyoxometalate Salts of Cationic Nitronyl Nitroxide Free Radicals

Abstract

Salts 1 and 2 that combine the [W6O19]2- Lindqvist anion with the cationicnitronyl nitroxide (NN) free radicals p-MepyNN+ and nBu3NCH2NN+ , respectively, havebeen synthesized and their structural and magnetic properties have been studied.
