The dependence of the energy of bound states of Frenkel excitons (biexcitons), in molecular crystals with one molecule per unit cell, on the number of neighbours is studied. It is shown that the number of bound states depends on the number of neighbours taken into account and the signs of their interaction energies with a fixed molecule.
