title: Gadolinium scandium germanide, Gd(2)Sc(3)Ge(4).
abstract: Gd(2)Sc(3)Ge(4) adopts the ortho-rhom-bic Pu(5)Rh(4)-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.
