The properties of systems with intermolecular interactions based on the model central forces with three-body interaction was studied. It is shown that the Axilrod-Teller potential is of limited use to describe the properties of two-center molecules. Use step function to describe the three-particle interaction led to a fixed coordination number at low temperatures. It has been shown that this model of intermolecular interaction is able to describe the high-temperature dissociation of diatomic molecules.
