- A method is devised of extracting the explicit form of the coupling between the primary and secondary order parameters with the use of experimental data and respecting classical and non-classical values of the effective critical exponents. The corresponding equation of state stems from the Ising model on a compressible lattice treated within the mean field approximation supplemented with terms ascertaining scaling invariance in the vicinity of the critical point. The theory is exemplified by the molecular ferroelectric crystals ($CH_{3}NH_{3})_{5}Bi_{2}Cl_{11}$ (MAPCB) and ($CH_{3}NH_{3})_{5}Bi_{2}Br_{11}$ (MAPBB).
