The compound C-60(InCl3)(2) is prepared by the interaction of C-60 and
InCl3. The resistivity is 150 Omega cm(-1) at room temperature. The t
emperature dependence of the conductivity between 4.2 and 300 K is exp
lained by the excitation from two energy levels. The excitation energi
es are 9 meV and 47 meV. (C) 1998 Elsevier Science Ltd.
