Title: Materials Data on KLiWO4 by Materials Project

Abstract

KLiWO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six O2- atoms to form distorted KO6 octahedra that share corners with four LiO4 tetrahedra, corners with six WO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of K–O bond distances ranging from 2.76–3.01 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 2.97–3.36 Å. In the third K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.73–3.09 Å. There are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share a cornercorner with one KO6 octahedra and corners with four WO4 tetrahedra. The corner-sharing octahedral tilt angles are 69°. There is one shorter (1.96 Å) and three longer (1.98 Å) Li–O bond length. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share a cornercorner withmore » one KO6 octahedra, corners with four WO4 tetrahedra, and an edgeedge with one KO6 octahedra. The corner-sharing octahedral tilt angles are 72°. There is two shorter (1.96 Å) and two longer (1.97 Å) Li–O bond length. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent KO6 octahedra and corners with four WO4 tetrahedra.

In the first W6+ site, W6+ is bonded to four O2- atoms to form WO4 tetrahedra that share corners with two equivalent KO6 octahedra and corners with four LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 64–74°. There is two shorter (1.81 Å) and two longer (1.82 Å) W–O bond length. In the second W6+ site, W6+ is bonded to four O2- atoms to form WO4 tetrahedra that share corners with two equivalent KO6 octahedra and corners with four LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 51–58°. There is one shorter (1.81 Å) and three longer (1.82 Å) W–O bond length. In the third W6+ site, W6+ is bonded to four O2- atoms to form WO4 tetrahedra that share corners with two equivalent KO6 octahedra and corners with four LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–76°. All W–O bond lengths are 1.82 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+, one Li1+, and one W6+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two K1+, one Li1+, and one W6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one K1+, one Li1+, and one W6+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two K1+, one Li1+, and one W6+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one K1+, one Li1+, and one W6+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two K1+, one Li1+, and one W6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+, one Li1+, and one W6+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one K1+, one Li1+, and one W6+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one Li1+, and one W6+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one Li1+, and one W6+ atom. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+, one Li1+, and one W6+ atom. In the twelfth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one Li1+, and one W6+ atom.« less
