Monomers and Dimers of Fullerenes in the Radical Anion Salts with Dye: (Astrophloxine+)2{C60(•-)}2 and (Astrophloxine+)2{C70(-)}2. Suppression of the C60(•-) Dimerization by π-Stacking

Radical anion salts of fullerenes have been obtained through the reaction of Cs.C60 and Cs.C70 with cationic dye (astrophloxine+)(I-) yielding crystalline salts (astrophloxine+)2P{C60(•-)}2.C6H4Cl2.C6H14 (1) and (astrophloxine+)2{C70(-)}2 (2). Salt 1 contains...
