Abstract
The preparation and characterization of new organic radical anions TEMPO-NH SO3- (tsfa) and TEMPO-OSO3- (tosu), which consist of the organic stable rad ical (TEMPO) and the anionic functional group (-NHSO3- or -OSO3-), has been investigated. The molecular and crystal structures of bis(triphenylphospho ranylidene)ammonium determined by X-ray analysis indicate that tsfa exists as a monovalent anion. Black powders of the TTF(.)tsfa and TTF(.)tosu salts were obtained, in each of which the donor to anion ratio is found to be 1 : 1 by elemental analysis. TTF(.)tsfa shows a weak antiferromagnetic intera ction with C = 0.360 emu M mol(-1) and theta = -0.52 K.
