The compound described by Gd3Sm is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to eight Gd(1,1) and four equivalent Sm(1) atoms to form GdSm4Gd8 cuboctahedra that share corners with four equivalent Sm(1)Gd12 cuboctahedra; corners with fourteen Gd(1,1)Sm4Gd8 cuboctahedra; edges with six equivalent Sm(1)Gd12 cuboctahedra; edges with twelve Gd(1,1)Sm4Gd8 cuboctahedra; faces with four equivalent Sm(1)Gd12 cuboctahedra; and faces with sixteen Gd(1,1)Sm4Gd8 cuboctahedra. In the second Gd site, Gd(1) is bonded to eight equivalent Gd(1) and four equivalent Sm(1) atoms to form GdSm4Gd8 cuboctahedra that share corners with four equivalent Sm(1)Gd12 cuboctahedra; corners with fourteen Gd(1,1)Sm4Gd8 cuboctahedra; edges with six equivalent Sm(1)Gd12 cuboctahedra; edges with twelve equivalent Gd(1)Sm4Gd8 cuboctahedra; faces with four equivalent Sm(1)Gd12 cuboctahedra; and faces with sixteen Gd(1,1)Sm4Gd8 cuboctahedra. Sm(1) is bonded to twelve Gd(1,1) atoms to form SmGd12 cuboctahedra that share corners with six equivalent Sm(1)Gd12 cuboctahedra; corners with twelve equivalent Gd(1)Sm4Gd8 cuboctahedra; edges with eighteen Gd(1,1)Sm4Gd8 cuboctahedra; faces with eight equivalent Sm(1)Gd12 cuboctahedra; and faces with twelve Gd(1,1)Sm4Gd8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
