Thermodynamics of bis-(η6-diphenyl)chromium (I) fulleride [(η6-Ph2)2Cr]+[C60].- in the range from T->(0 to 360)K

In the present work, the temperature dependence of heat capacity Cp,mo=f(T) of crystalline bis-(η6-diphenyl)chromium (I) fulleride [(η6-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=0.1MPa) thermodynamic functions Cp,mo/R, Δ0THmo/RT, Δ0TSmo/R and Φmo/R=Δ0TSmo/R-Δ0THmo/RT (where R is the universal gas constant) in the range T->(0 to 360)K
