Abstract:	The structures of B₂O₂(g), B₂S₂(g), Al₂O₂(g) and other aluminum family chalcogenides of the M₂X₂ species (X  S, Se, Te), have been investigated on the basis of thermochemical considerations. Contrary to previous postulations, the preponderance of thermochemical evidence suggest a bent M-X-M-X configuration for these gaseous species. The fundamental frequencies and free energy functions for B₂O₂(g) and Al₂O₂(g) are calculated and the atomization energy of Al₂O₂(g) is estimated to be less than 484 kcal mole⁻¹.
