The material structure described by (ZnSeO4)2O2 crystallizes in the monoclinic P2_1/c space group. The structure consists of two hydrogen peroxide molecules inside a ZnSeO4 framework. In the ZnSeO4 framework, Zn(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form ZnO4 tetrahedra that share corners with four equivalent Se(1)O4 tetrahedra and  an edgeedge with one Zn(1)O4 tetrahedra. Se(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SeO4 tetrahedra that share corners with four equivalent Zn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Zn(1) and one Se(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Zn(1) and one Se(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Zn(1) and one Se(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one Se(1) atom. is represented by the CIF file [CIF]
