The corner-sharing octahedra tilt angles range from 5–36°. There are a spread of Mo–O bond distances ranging from 1.84–2.08 Å. In the third Mo5+ site, Mo5+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with three equivalent MoO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 5–36°. There are a spread of Mo–O bond distances ranging from 1.80–2.19 Å. In the fourth Mo5+ site, Mo5+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with three equivalent MoO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 5–36°. There are a spread of Mo–O bond distances ranging from 1.80–2.19 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four MoO6 octahedra. The corner-sharing octahedra tilt angles range from 23–50°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four MoO6 octahedra. The corner-sharing octahedra tilt angles range from 23–50°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. There are sixteen inequivalent O2- sites.
