Materials Data on KP2(W3O11)2 by Materials Project

KP2(W3O11)2 is Potassium Silver Cyanide-like structured and crystallizes in the monoclinic Pm space group. The structure is three-dimensional. K1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of K–O bond distances ranging from 2.71–3.40 Å. There are six inequivalent W+5.50+ sites. In the first W+5.50+ site, W+5.50+ is bonded to six O2- atoms to form WO6 octahedra that share corners with three WO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 1–12°. There are a spread of W–O bond distances ranging from 1.82–2.09 Å. In the second W+5.50+ site, W+5.50+ is bonded to six O2- atoms to form WO6 octahedra that share corners with three WO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 2–13°. There are a spread of W–O bond distances ranging from 1.82–2.09 Å. In the third W+5.50+ site, W+5.50+ is bonded to six O2- atoms to form WO6 octahedra that share corners with five WO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 3–13°. There are a spread of W–O bond distances ranging from 1.86–2.10 Å. In the fourth W+5.50+ site, W+5.50+ is bonded to six O2- atoms to form WO6 octahedra that share corners with five WO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 3–12°. There are a spread of W–O bond distances ranging from 1.87–2.09 Å. In the fifth W+5.50+ site, W+5.50+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. There are a spread of W–O bond distances ranging from 1.93–2.02 Å. In the sixth W+5.50+ site, W+5.50+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. There are a spread of W–O bond distances ranging from 1.91–2.02 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 WO6 octahedra. The corner-sharing octahedra tilt angles range from 15–39°. There is three shorter (1.54 Å) and one longer (1.57 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 WO6 octahedra. The corner-sharing octahedra tilt angles range from 17–40°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are fifteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one K1+, one W+5.50+, and one P5+ atom.
