Bi2(SO4)3 crystallizes in the monoclinic C2/c space group. Bi(1) is bonded in a 9-coordinate geometry to one O(1), one O(4), one O(6), two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second S site, S(2) is bonded in a tetrahedral geometry to two equivalent O(5) and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Bi(1) and one S(1) atom. In the second O site, O(5) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one S(2) atom. In the third O site, O(6) is bonded in a distorted water-like geometry to one Bi(1) and one S(2) atom. In the fourth O site, O(1) is bonded in a distorted single-bond geometry to one Bi(1) and one S(1) atom. In the fifth O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one S(1) atom. In the sixth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one S(1) atom.
