Materials Data on K2Li14Zr3O14 by Materials Project
Abstract
K2Li14Zr3O14 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (3.01 Å) and two longer (3.10 Å) K–O bond lengths. There are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share a cornercorner with one ZrO6 octahedra, corners with seven LiO4 tetrahedra, edges with two ZrO6 octahedra, and edges with three LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 67°. There are a spread of Li–O bond distances ranging from 1.97–2.13 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four ZrO6 octahedra, corners with six LiO4 tetrahedra, and edges with five LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 19–38°. There is two shorter (1.96 Å) and two longer (1.98 Å) Li–O bond length. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with three ZrO6 octahedra, corners with five LiO4 tetrahedra, an edgeedge with one ZrO6 octahedra, and edges with three LiO4 tetrahedra.more »

In the second Zr4+ site, Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with ten LiO4 tetrahedra, an edgeedge with one ZrO6 octahedra, and edges with six LiO4 tetrahedra. There are a spread of Zr–O bond distances ranging from 2.07–2.31 Å. There are four inequivalent O2- sites.

In the second O2- site, O2- is bonded in a 7-coordinate geometry to two equivalent K1+, four Li1+, and one Zr4+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one K1+, four Li1+, and one Zr4+ atom. In the fourth O2- site, O2- is bonded to six Li1+ and one Zr4+ atom to form distorted OLi6Zr hexagonal pyramids that share a cornercorner with one OLi6Zr hexagonal pyramid, an edgeedge with one OLi6Zr hexagonal pyramid, and edges with four equivalent OLi3Zr2 square pyramids.},
