Y2PS is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Y(1) is bonded to three equivalent P(1) and three equivalent S(1) atoms to form a mixture of edge and corner-sharing YP3S3 octahedra. The corner-sharing octahedra are not tilted. P(1) is bonded to six equivalent Y(1) atoms to form PY6 octahedra that share corners with six equivalent S(1)Y6 octahedra, edges with six equivalent P(1)Y6 octahedra, and edges with six equivalent S(1)Y6 octahedra. The corner-sharing octahedral tilt angles are 2°. S(1) is bonded to six equivalent Y(1) atoms to form SY6 octahedra that share corners with six equivalent P(1)Y6 octahedra, edges with six equivalent P(1)Y6 octahedra, and edges with six equivalent S(1)Y6 octahedra. The corner-sharing octahedral tilt angles are 2°.
