3.1. Heat capacity
The C
p measurements were carried out between 6 K and 333 K
(Table 1S). The mass of the sample loaded in the calorimetric
ampoules of the BKT-3.0 device was 0.2949 g. A total of 168 experimental
C
p values was obtained in two series of experiments. The
heat capacity of the sample varied from 20% to 50% of the total heat
capacity of calorimetric (ampoule + substance) over the range
between 6 K and 333 K. The experimental points of C
p within the
temperature interval (20–333) K were fitted by means of the
least-squares method and polynomial equations (Eqs. (1)–(3)) of
the C
p versus temperature have been obtained. The corresponding
coefficients (A, B, C, etc.) are given i
