The compound described by TaPtTl is half-Heusler structured and crystallizes in the cubic F-43m space group. Ta(1) is bonded to four equivalent Pt(1) atoms to form TaPt4 tetrahedra that share corners with four equivalent Tl(1)Pt4 tetrahedra, corners with twelve equivalent Ta(1)Pt4 tetrahedra, and edges with six equivalent Tl(1)Pt4 tetrahedra. Pt(1) is bonded in a body-centered cubic geometry to four equivalent Ta(1) and four equivalent Tl(1) atoms. Tl(1) is bonded to four equivalent Pt(1) atoms to form distorted TlPt4 tetrahedra that share corners with four equivalent Ta(1)Pt4 tetrahedra, corners with twelve equivalent Tl(1)Pt4 tetrahedra, and edges with six equivalent Ta(1)Pt4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
