Hydrogenation of orthorhombic KHg2-type R(Cu,Ni)2 pseudobinary intermetallic compounds (R = Ce, Pr, Nd) was found to lead to the formation of an orthorhombic insertion-type hydride, which readily transforms into a hexagonal Fe2P-type hydride. This

Hydrides of the i 3- and R2Ni7-based (R = light rare earth element) intermetallics exhibit novel structural features. Structures of these hydrides, including CeNi3D2.8, La2Ni7D6.5, LaNi3D2.8, and Ce2Ni7D4.7, are formed via a huge volume expansion occ

The present work is focused on studies of the influence of magnesium on the hydrogenation behaviour of the (La,Mg) 2 Ni 7 alloys. Substitution of La in La 2 Ni 7 by Mg to form La 1.5 Mg 0.5 Ni 7 preserves the initial Ce 2 Ni 7 type of the hexagonal P
