The structure described by TaRuAs is half-Heusler structured and crystallizes in the cubic F-43m space group. Ta(1) is bonded in a body-centered cubic geometry to four equivalent Ru(1) and four equivalent As(1) atoms. Ru(1) is bonded to four equivalent Ta(1) atoms to form RuTa4 tetrahedra that share corners with four equivalent As(1)Ta4 tetrahedra, corners with twelve equivalent Ru(1)Ta4 tetrahedra, and edges with six equivalent As(1)Ta4 tetrahedra. As(1) is bonded to four equivalent Ta(1) atoms to form AsTa4 tetrahedra that share corners with four equivalent Ru(1)Ta4 tetrahedra, corners with twelve equivalent As(1)Ta4 tetrahedra, and edges with six equivalent Ru(1)Ta4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
