Abstract: The pressure-volume-temperature equations of state have been constructed by combining experimental data and semiempirical estimations for a number of compounds recently synthesized under extreme pressure-temperature conditions. The solids with various bonding types were considered: covalent hard and superhard boron-rich and diamond-like compounds (B$_6$O, B$_{13}$N$_2$, BP, cBC$_5$, and nano-cBN), ionic semiconductors (Mg$_2$C and Mg$_2$C$_3$), as well as intercalation compounds (clathrates Na$_4$Si$_{24}$ and Na$_{24+x}$S$_{136}$), and simple substances (γ-B$_{28}$ and t'-B$_{52}$ boron allotropes, Na and Mg metals, and open-framework silicon allotrope o-Si$_{24}$). We also showed how the reliable p-V-T equations of state may be constructed using different types of available data.
