The possible interstitial sites for hydrogen occupation in the intermetallic lattices of ZrPd2 (MoSi2 tetragonal structure type) and UPd3 (Ni3Ti hexagonal structure type) were identified by their Wyckoff notation and characterized by the metal atoms on the polyhedron vertices. Interstitial hole sizes and intersite distances were also calculated utilizing lattice constants and estimated atomic metal radii. It is concluded that hydrogen absorption is not restricted by geometrical factors imposed by empirical and theoretical criteria for the minimum hole size and intersite distance. The hydrogen inertness of the ZrPd2 and UPd3 compounds is discussed from the point of view of their large stabilities and the recently found correlations between bonding strengths and hydrogen absorption.
