Materials Data on Li3Nb4O12 by Materials Project
Li3Nb4O12 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Li sites. In the first Li site, Li is bonded in a 6-coordinate geometry to six O atoms. There are three shorter (2.06 Å) and three longer (2.42 Å) Li–O bond lengths. In the second Li site, Li is bonded in a 6-coordinate geometry to six O atoms. There are three shorter (2.08 Å) and three longer (2.41 Å) Li–O bond lengths. In the third Li site, Li is bonded in a distorted trigonal planar geometry to six O atoms. There are three shorter (2.01 Å) and three longer (2.56 Å) Li–O bond lengths. There are four inequivalent Nb sites. In the first Nb site, Nb is bonded to six O atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 24–40°. There are three shorter (1.91 Å) and three longer (2.12 Å) Nb–O bond lengths. In the second Nb site, Nb is bonded to six O atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 37–38°. There are three shorter (1.94 Å) and three longer (2.10 Å) Nb–O bond lengths. In the third Nb site, Nb is bonded to six O atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 37–40°. There are three shorter (1.93 Å) and three longer (2.12 Å) Nb–O bond lengths. In the fourth Nb site, Nb is bonded to six O atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 24–38°. There are three shorter (1.92 Å) and three longer (2.10 Å) Nb–O bond lengths. There are four inequivalent O sites. In the first O site, O is bonded in a distorted see-saw-like geometry to two Li and two Nb atoms. In the second O site, O is bonded in a distorted trigonal planar geometry to one Li and two Nb atoms. In the third O site, O is bonded in a distorted trigonal planar geometry to one Li and two Nb atoms. In the fourth O site, O is bonded in a 4-coordinate geometry to two Li and two Nb atoms.
