A. Perez-benitez et al., An easy and efficient method to grow single crystals of monoanionic C-60 salts on a copper surface, SYNTH METAL, 121(1-3), 2001, pp. 1157-1158
The facile and selective preparation of salts of C-60 monoanion as a single
crystals has been accomplished by using metallic copper as the reducing ag
ent in the presence of the electrolyte Ph4PBr. The salt (Ph4P)(2)C60Br, har
vested from the surface of a copper wire, has been characterized by electro
n paramagnetic resonance, Vis-NIR spectroscopy and X-ray crystal structure.
