New organic free radical anions TEMPO-A-CO-(o-,m-,p-)C6H4SO3-(A=NH,NCH3,O) and their TTF and/or BEDT-TTF salts

We have prepared eight TEMPO-containing anions TEMPO-A-CO-(n-)C6H4SO3- (n = o, m, p for A = NH (N1, N2, N3), n = o, p for A = NCH3 (M1, M3), and n = o, m, p for A = O (O1, O2, O3)) as PPh4 salts. Metathesis of their salts with (TTF)3(BF4)2 gave their TTF salts. Electrocrystallization of BEDT-TTF with PPh4 · M1 yielded the α-(BEDT-TTF)3(M1)2 · 8H2O salt. We report their crystal structures, electrical resistivities, and magnetic properties. The relation between crystal structures and physical properties are discussed.
