The crystal structure described by Y2(SO4)3 crystallizes in the trigonal R-3c space group. Y(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form YO6 octahedra that share corners with six equivalent S(1)O4 tetrahedra. S(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with four equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-27°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to one Y(1) and one S(1) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Y(1) and one S(1) atom. is represented by the CIF card [CIF]
