Materials Data on KLi3Zr2(Si2O5)6 by Materials Project
KLi3Zr2(Si2O5)6 crystallizes in the hexagonal P6/mcc space group. The structure is three-dimensional. K1+ is bonded in a 12-coordinate geometry to twelve equivalent O2- atoms. All K–O bond lengths are 3.10 Å. Li1+ is bonded to four equivalent O2- atoms to form distorted LiO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra and edges with two equivalent ZrO6 octahedra. All Li–O bond lengths are 1.98 Å. Zr4+ is bonded to six equivalent O2- atoms to form ZrO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with three equivalent LiO4 tetrahedra. All Zr–O bond lengths are 2.11 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one ZrO6 octahedra, a cornercorner with one LiO4 tetrahedra, and corners with three equivalent SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 37°. There are a spread of Si–O bond distances ranging from 1.61–1.64 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one K1+ and two equivalent Si4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Zr4+, and one Si4+ atom.
