In the present research, the low-temperature molar heat capacity, C-p,C-m degrees, of C-60 - L-lysine derivative was measured using adiabatic calorimetry from T = 13 K to T = 326 K. The respective molar third law entropy at T = 298.15 K, S-m degrees, was calculated giving (1110 +/- 3) J.K-1.mol(-1) for C-60 - L-lysine derivative. Smoothed C-p,C-m degrees (T) values between T -> 0 K and 320 K are presented along with the values for S-m degrees and the functions [H-m degrees (T) -H-m degrees (0)] and [G(m)degrees (T) - H-m degrees (0)]. The standard molar entropy of formation, Delta S-f(m)degrees, at T = 298.15 K was calculated for the compound under study in the crystalline state giving -1916 +/- 5 J.K-1.mol(-1). The complex thermal analysis of the C-60-Lys crystallohydrate was performed from T = 300 to T = 1323 K. (C) 2017 Elsevier Ltd.
