The structural transformations of the C 70 in benzene, toluene, and hexane solutions were studied. The X-ray powder diffraction experiments made directly on the C 70 solution samples showed structural transformations of similar types for all the tested solvents. It is shown that C 70 in benzene and hexane solution forms solvated phases at room temperature similar to the toluene solvate described before (Agafonov, V.; Ceolin, R.; Andre, D.; De Bruijn, J.; Gonthier-Vassal, A.; Szwarc, H.; Rodier, N.; Dugue, J.; Toscani, S.; Sizaret, P. Y.; Fabre, C.; Greugny, V.; Rassat, A. Chem. Phys. Lett. 1993, 208, 68). Experiments with C 70 crystallized from benzene solutions performed at room temperature resulted in the formation of the orthorhombic solvated phase, while crystals grown at T > 40 °C appeared to be a mixture of the pure C 70 hcp phase and the monoclinic solvate phase.
