description: Rb2Mo3P3O17 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to eleven O2- atoms. There are a spread of Rb–O bond distances ranging from 3.09–3.70 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.29 Å. There are three inequivalent Mo+5.67+ sites. In the first Mo+5.67+ site, Mo+5.67+ is bonded to six O2- atoms to form distorted MoO6 octahedra that share corners with five PO4 tetrahedra.

In the second Mo+5.67+ site, Mo+5.67+ is bonded to six O2- atoms to form distorted MoO6 octahedra that share a cornercorner with one MoO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 31°. There are a spread of Mo–O bond distances ranging from 1.73–2.22 Å. In the third Mo+5.67+ site, Mo+5.67+ is bonded to six O2- atoms to form distorted MoO6 octahedra that share a cornercorner with one MoO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedral tilt angles are 31°. There are a spread of Mo–O bond distances ranging from 1.74–2.27 Å. There are three 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 21–51°. There are a spread of P–O bond distances ranging from 1.54–1.56 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 30–46°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. In the third 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 35–45°.
