NaZn4H6SO14ClO2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two hydrogen peroxide molecules and one NaZn4H6SO14Cl framework. In the NaZn4H6SO14Cl framework, Na is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Na–O bond distances ranging from 2.44–2.84 Å. There are four inequivalent Zn sites. In the first Zn site, Zn is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Zn–O bond distances ranging from 2.05–2.16 Å. In the second Zn site, Zn is bonded to six O atoms to form ZnO6 octahedra that share a cornercorner with one SO4 tetrahedra, corners with two equivalent ZnClO3 tetrahedra, and edges with three ZnO6 octahedra.
