- Аннотация: This work proposes a new vision on the description of heat capacities of diamond-like compounds with sphalerite structure. The 4th group of diamond-like elements consists of, in addition to diamond, silicon, germanium, alpha tin, and diamond-like lead. Flerovium (114Fl) closes this group. There should be no other elements in this group according to the fine structure constant or the Sommerfeld constant α. In this case, the sphalerite structure has the ultimate value of the heat capacity Ср =30.5 J mol-at-1 K-1 or 3.67 R, and it falls on 114th element (114Fl). This quantity arises when plotting the isotherms Ln (Cp/R) vs Ln(N). The heat capacities of sphalerite phases were considered as a single system.
