ABSTRACT

In the present work, the temperature dependence of heat capacity C_p;m 1/4 f oT P of crystalline bis-(n6-diphenyl)chromium (I) fulleride [(n6-Ph2)2Cr]+[C60]__ has been measured by precision adiabatic vacuum calorimetry between T = (6 and 360) K with an uncertainty of +-0.2%. In this temperature interval, the transformations were detected and their thermodynamic characteristics were estimated. The experimental data were used for calculating standard (po = 0.1 MPa) thermodynamic functions C_p;m=R, DT 0H_m=RT , DT 0 S_m=R and U_m=R 1/4 DT 0 S_m=R _ DT 0H_m=RT (where R is the universal gas constant) in the range T! (0 to 360) K.
