A new approach for the synthesis of magnetic materials based on nitroxide free radicals and inorganic coordination polymers

The use of nitronyl nitroxide (NN) radicals as spectators inside extended i norganic magnetic lattices is described. Two possibilities are presently be ing explored, namely, the design of oxalato-bridged bimetallic networks by using cationic NN radicals of the N-alkylpyridinium type as templating agen ts, and the design of bimetallic lattices based on hexacyanometalates and n ickel(II) diaminocomplexes incorporating anionic NN radicals of the carboxy phenyl type.
