The structure described by Sb2(SO4)3 crystallizes in the trigonal R-3c space group. Sb(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form SbO6 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 Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 22-40°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one S(1) atom. In the second O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
