description: Cs2Mo3P5O19 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 2.94–3.57 Å. In the second Cs1+ site, Cs1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.23–3.82 Å. There are two inequivalent Mo+3.67+ sites. In the first Mo+3.67+ site, Mo+3.67+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Mo–O bond distances ranging from 2.09–2.17 Å. In the second Mo+3.67+ site, Mo+3.67+ is bonded to six O2- atoms to form MoO6 octahedra that share a cornercorner with one MoO6 octahedra and corners with five PO4 tetrahedra. The corner-sharing octahedral tilt angles are 26°. There are a spread of Mo–O bond distances ranging from 1.88–2.12 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 39–43°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three MoO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 19–48°. There are a spread of P–O bond distances ranging from 1.51–1.64 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three MoO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 9–46°. There are a spread of P–O bond distances ranging from 1.51–1.63 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two P5+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted linear geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cs1+ and two equivalent Mo+3.67+ atoms. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Mo+3.67+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Mo+3.67+, and one P5+ atom.
