For R2M7 (R = rare-earth metal, M = Fe, Co, Ni, Zn) intermetallic compounds or multicomponent solid solutions based on them polymorphism is often characteristic. For example, for Tb2Ni7 structural transition from hexagonal Ce2Ni7 to rhombohedral Gd2Co7 at 931 ℃ is known [1]. Both polymorph modifications mainly dissolve Li, Mg, or some p-elements approximately in equal quantities. The hydrogen sorption properties are inherent to these phases.
