In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two SbO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–66°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the fifth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two SbO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 34–73°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. There are sixteen inequivalent O2- sites.
