The crystal structure described by ZnSeO4 crystallizes in the orthorhombic Pnma space group. Zn(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. Se(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one Se(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one 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. is represented by the CIF card [CIF]
