Abstract
Electrical conductivity measurements on aqueous solutions of the lithium salt of fullerenehexamalonic acid, Th-C66(COOLi)12, were carried out at four temperatures: 5, 15, 25, and 35°C, and in the concentration range from about 0.2 to 0.00014 mol (COO-)/dm3. The limiting equivalent conductivities of the fullerenehexamalonate anion were estimated at the temperatures of our measurements. Temperature dependence of the molar conductivity of Th-C66(COOLi)12 can be satisfactorily explained by changed viscosity of the solution. Molar conductivities of lithium fullerenehexamalonate are compared with those of sodium and calcium fullerenehexamalonates.
