Zn2SO6 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(1), one O(2), one O(3), and two equivalent O(4) atoms to form distorted ZnO5 trigonal bipyramids that share corners with three equivalent Zn(2)O4 tetrahedra, corners with three equivalent S(1)O4 tetrahedra, and corners with two equivalent Zn(1)O5 trigonal bipyramids. In the second Zn site, Zn(2) is bonded to one O(2), one O(4), one O(5), and one O(6) atom to form distorted ZnO4 tetrahedra that share corners with two equivalent S(1)O4 tetrahedra and corners with three equivalent Zn(1)O5 trigonal bipyramids. S(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form SO4 tetrahedra that share corners with two equivalent Zn(2)O4 tetrahedra and corners with three equivalent Zn(1)O5 trigonal bipyramids. There are six inequivalent O sites. In the first O site, O(6) is bonded in a single-bond geometry to one Zn(2) atom. In the second O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one S(1) atom. In the third O site, O(2) is bonded in a distorted trigonal planar geometry to one Zn(1), one Zn(2), and one S(1) atom. In the fourth O site, O(3) is bonded in a bent 150 degrees geometry to one Zn(1) and one S(1) atom. In the fifth O site, O(4) is bonded in a trigonal planar geometry to one Zn(2) and two equivalent Zn(1) atoms. In the sixth O site, O(5) is bonded in a bent 150 degrees geometry to one Zn(2) and one S(1) atom.
