An approach to constructing semiempirical equations of state of molecular crystals of nitro compounds is suggested allowing one to describe isothermal compression of the crystal of triaminotrinitrobenzene (1,3,5-triamino-2,4,6- trinitrobenzene) by the familiar modulus of three-dimensional compression and sublimation heat of the crystal obtained from experiments not related to isothermal compression. A comparative analysis of experimental data on isothermal compression of the molecular crystal of triaminotrinitrobenzene and calculations by the proposed equation of state have shown that the experimental and calculated values of pressure are within the limits of experimental uncertainty.
