摘要

The magnesium-rich intermetallic compounds RETMg_2 (RE = La, Pr,Nd; T = Ni, Pd, Pt) were obtained by melting of the elements in sealed tantalum ampoules and subsequent annealing. Their structures have been characterized on the basis of powder X-ray diffraction. The RETMg_2 phases crystallize with the orthorhombic MgCuAl_2-type structure, space group Cmcm. The crystal chemical peculiarities are briefly discussed.
