Abstract
A ternary alloy comprised of zirconium, manganese and a third element selected from cerium, praseodymium and neodymium is characterized in having AB.sub.2 hexagonal crystal structure and stoichiometry. Members of a preferred class of compounds, represented by the empirical formula Zr.sub.x-1 M.sub.x Mn.sub.2 wherein 'x' has a value between zero and about 0.3 and M is one of the selected metals, are particularly suitable for use as hydrogen storage materials.
