N2 - The solubilities of buckminsterfullerene, C60, at 298 and 303 K and of sulfur hexafluoride, SF6, at 298 K in various solvents, obtained from the literature, were submitted to stepwise linear regression analysis with respect to the relevant solvent properties. Different sets of properties were found to govern the solubilities of these two substances. In the case of C60 the solvent polarizability (expressed by the molar refraction and the π* solvatochromic parameter) helps the solubility and the solvent polarity (expressed by the dipole moment and the ET(30) solvatochromic parameter) counteracts it. On the contrary, the solubility of SF6 is mainly affected (adversely) by the surface tension of the solvent, and somewhat assisted by its polarizability and hampered by its polarity. These findings are rationalized in terms of the physicochemical interactions that take place in these systems.
