Abstract
The applicability of the simplest cluster models for semi-quantitative descriptions of the thermodynamics of structural phase transitions in quasi–one-dimensional ferroelectrics is considered. A lead hydrogen phosphate is used as an example. Even such simple models can qualitatively and, in some cases, quantitatively reproduce experimental data.
