Gadolinium scandium germanide, Gd₂Sc₃Ge₄

S. Misra and G. J. Miller

Abstract: Gd₂Sc₃Ge₄ adopts the orthorhombic Pu₅Rh₄-type structure. The crystal structure contains six sites in the asymmetric unit: two sites are statistically occupied by rare-earth atoms with Gd:Sc ratios of 0.967 (4):0.033 (4) and 0.031 (3):0.969 (3), one site (.m. symmetry) is occupied by Sc atoms, and three distinct sites (two of which with .m. symmetry) are occupied by Ge atoms. The rare-earth atoms form two-dimensional slabs with Ge atoms occupying the trigonal-prismatic voids.
