The compound described by CuAsTe crystallizes in the orthorhombic Pnma space group. Cu(1) is bonded to one As(1) and three equivalent Te(1) atoms to form CuTe3As tetrahedra that share  a cornercorner with one Te(1)Cu3As tetrahedra, corners with five equivalent As(1)CuTeAs2 tetrahedra, and corners with six equivalent Cu(1)Te3As tetrahedra. As(1) is bonded to one Cu(1), two equivalent As(1), and one Te(1) atom to form distorted AsCuTeAs2 tetrahedra that share corners with two equivalent As(1)CuTeAs2 tetrahedra, corners with five equivalent Cu(1)Te3As tetrahedra, and corners with five equivalent Te(1)Cu3As tetrahedra. Te(1) is bonded to three equivalent Cu(1) and one As(1) atom to form TeCu3As tetrahedra that share  a cornercorner with one Cu(1)Te3As tetrahedra, corners with five equivalent As(1)CuTeAs2 tetrahedra, and corners with six equivalent Te(1)Cu3As tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
