摘要：

M3X3-type rare earth silicides crystallize in Cr5B3-type tetragonal (La-Nd) and Mn5Si3-type hexagonal structures (Sm-Lu except Eu). The corresponding germanides are all (except Eu and Yb) of the Mn5Si3 type. Atomic parameters of the Mn5Si3-type structure were determined, and the interatomic distances were calculated. M3X3C ternary phases were obtained for the Mn5Si3-type compounds with the same hexagonal structure but different lattice size. Geometrical arguments show that carbon occupies the octahedral holes of the hexagonal lattice. © 1969, American Chemical Society. All rights reserved.
