New intermetallic compounds RE 4 T Cd (RE = Y, La-Nd, Sm, Gd-Tm, Lu; T = Ni, Pd, Ir, Pt) were synthesized by melting of the elements in sealed tantalum tubes in a highfrequency furnace. They crystallize with the Gd 4 RhIn-type structure, space group F43m, Z = 16. The four gadolinium compounds were characterized by single crystal X-ray diffractometer data: a = 1361.
