Materials Data on K2YTi(PO4)3 by Materials Project
K2YTi(PO4)3 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.94–3.12 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 3.00–3.28 Å. Y3+ is bonded to six O2- atoms to form YO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are three shorter (2.22 Å) and three longer (2.24 Å) Y–O bond lengths. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent PO4 tetrahedra. There is three shorter (1.96 Å) and three longer (2.01 Å) Ti–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent YO6 octahedra and corners with two equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 9–40°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Y3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to two K1+, one Ti4+, and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Ti4+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one Y3+, and one P5+ atom.
