Abstract
The temperature dependence of the heat capacity at second-order phase transitions that were previously detected in the [Zn2(C8H4O4)2 · C6H12N2] metal-organic framework compound has been analyzed. The critical exponents have been obtained. It has been shown that the behavior of the heat capacity below the critical temperature of 60 K, which is attributed to the violation of the mirror symmetry of C2H12N6 molecules, is exponential.
