The structure described by Rh4AsP is half-Heusler-like structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to one As(1) and three equivalent P(1) atoms to form distorted RhAsP3 tetrahedra that share corners with six equivalent Rh(2)As3P tetrahedra, corners with ten equivalent Rh(1)AsP3 tetrahedra, edges with three equivalent Rh(2)As3P tetrahedra, and edges with three equivalent Rh(1)AsP3 tetrahedra. In the second Rh site, Rh(2) is bonded to three equivalent As(1) and one P(1) atom to form distorted RhAs3P tetrahedra that share corners with six equivalent Rh(1)AsP3 tetrahedra, corners with ten equivalent Rh(2)As3P tetrahedra, edges with three equivalent Rh(2)As3P tetrahedra, and edges with three equivalent Rh(1)AsP3 tetrahedra. As(1) is bonded in a body-centered cubic geometry to two equivalent Rh(1) and six equivalent Rh(2) atoms. P(1) is bonded in a body-centered cubic geometry to two equivalent Rh(2) and six equivalent Rh(1) atoms. is represented by the CIF card [CIF]
