description: Mo3Tl2P3O17 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. 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. There are a spread of Mo–O bond distances ranging from 1.71–2.19 Å. 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 1.73–2.24 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 1.74–2.26 Å. There are two inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Tl–O bond distances ranging from 3.08–3.48 Å. In the second Tl1+ site, Tl1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Tl–O bond distances ranging from 2.88–3.26 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 is two shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. 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 29–47°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. 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 35–46°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. There are seventeen inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo+5.67+ and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Mo+5.67+, one Tl1+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+5.67+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Mo+5.67+ and one Tl1+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Mo+5.67+ and two Tl1+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+5.67+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Mo+5.67+, two Tl1+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mo+5.67+, one Tl1+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one Mo+5.67+ and two equivalent Tl1+ atoms. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Mo+5.67+, two Tl1+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to one Mo+5.67+, one Tl1+, and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+5.67+, one Tl1+, and one P5+ atom. In the thirteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Mo+5.67+ atoms. In the fourteenth O2- site, O2- is bonded in a 2-coordinate geometry to one Mo+5.67+, one Tl1+, and one P5+ atom.
