The structure described by Bi2SO7 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to one O(3), one O(7), two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. In the second Bi site, Bi(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(6) atom. S(1) is bonded in a tetrahedral geometry to one O(4), one O(5), one O(6), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(6) is bonded in a distorted single-bond geometry to one Bi(2) and one S(1) atom. In the second O site, O(7) is bonded in a single-bond geometry to one Bi(1) and one S(1) atom. In the third O site, O(1) is bonded in a trigonal planar geometry to one Bi(2) and two equivalent Bi(1) atoms. In the fourth O site, O(2) is bonded in a trigonal planar geometry to one Bi(2) and two equivalent Bi(1) atoms. In the fifth O site, O(3) is bonded in a bent 150 degrees geometry to one Bi(1) and one Bi(2) atom. In the sixth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one S(1) atom. In the seventh O site, O(5) is bonded in a distorted single-bond geometry to one Bi(2) and one S(1) atom. is represented by the CIF card [CIF]
