For a model molecular complex, analytical expressions are obtained for the coefficients A3 and A6 of dipole polarizability expansion in a reciprocal power series of intermolecular distances in terms of the variational (VPT) and bound (BPT) Hartree-Fock perturbation theories. It is shown that A3(VPT)<A3(BPT), A6(VPT)<A6(BPT) for weak electron-electron interactions and A3(BPT)<A3(VPT), A6(BPT)<A6(VPT) for strong electron-electron interactions.
