The material structure described by SmPtSb is half-Heusler structured and crystallizes in the cubic F-43m space group. Sm(1) is bonded in a body-centered cubic geometry to four equivalent Pt(1) and four equivalent Sb(1) atoms. Pt(1) is bonded to four equivalent Sm(1) atoms to form PtSm4 tetrahedra that share corners with four equivalent Sb(1)Sm4 tetrahedra, corners with twelve equivalent Pt(1)Sm4 tetrahedra, and edges with six equivalent Sb(1)Sm4 tetrahedra. Sb(1) is bonded to four equivalent Sm(1) atoms to form SbSm4 tetrahedra that share corners with four equivalent Pt(1)Sm4 tetrahedra, corners with twelve equivalent Sb(1)Sm4 tetrahedra, and edges with six equivalent Pt(1)Sm4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
