RuTeSe is half-Heusler structured and crystallizes in the cubic F-43m space group. Ru(1) is bonded to four equivalent Se(1) atoms to form distorted RuSe4 tetrahedra that share corners with four equivalent Te(1)Se4 tetrahedra, corners with twelve equivalent Ru(1)Se4 tetrahedra, and edges with six equivalent Te(1)Se4 tetrahedra. Te(1) is bonded to four equivalent Se(1) atoms to form distorted TeSe4 tetrahedra that share corners with four equivalent Ru(1)Se4 tetrahedra, corners with twelve equivalent Te(1)Se4 tetrahedra, and edges with six equivalent Ru(1)Se4 tetrahedra. Se(1) is bonded in a body-centered cubic geometry to four equivalent Ru(1) and four equivalent Te(1) atoms.
