The ordered structure model recently proposed by Overhauser (Phys. Rev. B 35, 411 (1987)) for lithium beryllium trihydride, LiBeH/sub 3/, gives results in disagreement with the x-ray powder-diffraction data reported by Bell and Coates (J. Chem. Soc. (A) 1968, 628 (1968)). In this note, we present a disordered structure model which closely fits the experimental data, but is unlikely on structural chemistry grounds. New diffraction data on LiBeH/sub 3/ are required to ascertain its structure and existence.
