hexachloroantimonate was used as an one electron oxidant to prepare single crystals of N-Me- (I), N-Et- (II), N-n-Bu-, N-Ph- and N-p-nitrophenylphenothiazine radical cation hexachloroantimonates resp. Mol. structure of I and II were evaluated by x-ray diffraction anal. It is shown that the configuration of the radical cations are quite different from those of their neutral mols., indicating that strong conjugative and hyperconjugative effects are present in the radical cations.
