Title: Materials Data on Li4Nb3Cu3(TeO8)2 by Materials Project

Abstract

Li4Nb3Cu3(TeO8)2 is Hausmannite-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four CuO6 octahedra and corners with five NbO6 octahedra. The corner-sharing octahedra tilt angles range from 44–63°. There are a spread of Li–O bond distances ranging from 2.03–2.27 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share a cornercorner with one CuO6 octahedra, corners with two equivalent NbO6 octahedra, an edgeedge with one NbO6 octahedra, and edges with two equivalent CuO6 octahedra. The corner-sharing octahedral tilt angles are 62°. There are a spread of Li–O bond distances ranging from 2.00–2.11 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share a cornercorner with one NbO6 octahedra, corners with two equivalent CuO6 octahedra, an edgeedge with one CuO6 octahedra, and edges with two equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 67–70°. There are a spread of Li–O bond distances ranging from 1.99–2.10 Å.
