✦ Synopsis
The facile and simple wet-chemical synthesis of single crystals of alkali metal doped fnllerenes was developed by means of diffusion in organic solvents of C,, and alkali metal tetraphenylborate. The single crystals M,C,,(THF), (M = Na, K) posess a hexagonal unit cell and ESR showed the existence of a typical broad C, anion radical signal, in addition to a small sharp signal which is amenable to microwave power saturation. The existence of the spike signal is almost always involved in fullerene anion radical systems. The solid-state 23Na and solid-state 13C NMR on Na,C,,(THF), also revealed the homogeneity of the single crystal.
