UO2SO4 crystallizes in the monoclinic P2_1/c space group. U(1) is bonded to one O(1), one O(3), one O(4), one O(5), one O(6), and two equivalent O(2) atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent U(1)O7 pentagonal bipyramids and corners with four equivalent S(1)O4 tetrahedra. S(1) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form SO4 tetrahedra that share corners with four equivalent U(1)O7 pentagonal bipyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one U(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent U(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one U(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one U(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one U(1) and one S(1) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one U(1) and one S(1) atom.
