In the present paper, an attempt has been made for the comparative study of different equations of state and investigated the thermodynamic and thermoelastic properties for C 60 crystalline solid. We have fitted the experimental compression curve to the modified Tait’s equation of state. Using the best fit values of B 0 and B 0 ′, we have computed the compression behavior of C 60 crystalline solid in the face-centered-cubic structure in the pressure range of 0–11 GPa at room temperature. Tait’s EOS has further extended to analyze the temperature dependence of thermal expansivity and bulk modulus for C 60 crystalline solid. We have attempted for theoretical prediction of pressure-dependent Grüneisen parameter and isothermal bulk modulus for C 60 crystalline solid at reference temperature. The calculated values of thermal expansion are in good agreement with the available theoretical and experimental results, which reveals the validity of present work. The results of the coefficient of thermal expansion achieved in the present study are found to display good agreement with other available results. The present relationship of thermal expansivity may be used to understand the temperature behavior of nanomaterials.
