A theorem is proved which shows that the existence of H2 and Ps2 molecules is a sufficient condition for the existence of arbitrary four-body (or quasi-four-body) molecules. It is also shown that the bound-states of H2 and Ps2 are rigorous lower and upper bounds, respectively, for the exact energies of the bound-states of all other previously mentioned molecules. The consequences of the preceding theorem and corollary in astrophysics, solid state physics and quantum chemistry are briefly discussed.
