description: Ba3(P3O11)2O2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two hydrogen peroxide molecules and one Ba3(P3O11)2 framework. In the Ba3(P3O11)2 framework, there are three inequivalent Ba sites. In the first Ba site, Ba is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ba–O bond distances ranging from 2.60–3.24 Å. In the second Ba site, Ba is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Ba–O bond distances ranging from 2.70–3.15 Å. In the third Ba site, Ba is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Ba–O bond distances ranging from 2.66–3.13 Å. There are six inequivalent P sites. In the first P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the second P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.63 Å. In the third P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.66 Å. In the fourth P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.63 Å. In the fifth P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.62 Å. In the sixth P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.63 Å. There are twenty-two inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two P atoms.

In the fourteenth O site, O is bonded in a distorted single-bond geometry to one Ba and one P atom. In the fifteenth O site, O is bonded in a distorted single-bond geometry to two Ba and one P atom. In the sixteenth O site, O is bonded in a distorted single-bond geometry to one Ba and one P atom. In the seventeenth O site, O is bonded in a distorted bent 150 degrees geometry to one Ba and one P atom. In the eighteenth O site, O is bonded in a distorted single-bond geometry to two Ba and one P atom. In the nineteenth O site, O is bonded in a bent 120 degrees geometry to two Ba atoms.
