Abstract

ZnO2Zn3(SO4)4(O2)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two hydrogen peroxide molecules; one Zn3(SO4)4 sheet oriented in the (0, 1, 0) direction; and one zinc dihydroxide molecule. In the Zn3(SO4)4 sheet, there are two inequivalent Zn sites. In the first Zn site, Zn is bonded in a linear geometry to four O atoms. There are two shorter (1.81 Å) and two longer (2.59 Å) Zn–O bond lengths. In the second Zn site, Zn is bonded in a tetrahedral geometry to four O atoms. There are a spread of Zn–O bond distances ranging from 1.95–2.04 Å. There are two inequivalent S sites. In the first S site, S is bonded in a trigonal non-coplanar geometry to three O atoms. There is one shorter (1.47 Å) and two longer (1.51 Å) S–O bond length. In the second S site, S is bonded in a trigonal non-coplanar geometry to three O atoms. There is two shorter (1.52 Å) and one longer (1.64 Å) S–O bond length. There are eight inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one S atom. In the second O site, O is bonded in a bent 120 degrees geometry to one Zn and one S atom. In the third O site, O is bonded in a bent 120 degrees geometry to one Zn and one S atom. In the fourth O site, O is bonded in a bent 120 degrees geometry to one Zn and one S atom. In the fifth O site, O is bonded in a bent 120 degrees geometry to one Zn and one S atom. In the sixth O site, O is bonded in a bent 120 degrees geometry to one Zn and one S atom. In the seventh O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 1.23 Å. In the eighth O site, O is bonded in a water-like geometry to one Zn and one O atom.
