Abstract

Li3La5Ti6Nb2O26 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.68 Å. In the second Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.96–2.69 Å. There are three inequivalent La3+ sites.

In the sixth O2- site, O2- is bonded to three Li1+ and one Nb5+ atom to form distorted OLi3Nb trigonal pyramids that share corners with four equivalent OLi3Ti tetrahedra, a cornercorner with one OLi3Nb trigonal pyramid, an edgeedge with one OLi3Ti tetrahedra, and an edgeedge with one OLi3Nb trigonal pyramid. In the seventh O2- site, O2- is bonded in a distorted linear geometry to three La3+ and two Ti4+ atoms. In the eighth O2- site, O2- is bonded in a distorted linear geometry to two equivalent La3+ and two equivalent Ti4+ atoms. In the ninth O2- site, O2- is bonded in a distorted linear geometry to two equivalent La3+ and two equivalent Ti4+ atoms.

In the eleventh O2- site, O2- is bonded in a distorted linear geometry to three La3+ and two Ti4+ atoms. In the twelfth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, two La3+, one Ti4+, and one Nb5+ atom. In the thirteenth O2- site, O2- is bonded in a 1-coordinate geometry to four La3+ and two Ti4+ atoms. In the fourteenth O2- site, O2- is bonded to three Li1+ and one Ti4+ atom to form OLi3Ti tetrahedra that share a cornercorner with one OLi3Ti tetrahedra, corners with four equivalent OLi3Nb trigonal pyramids, an edgeedge with one OLi3Ti tetrahedra, and an edgeedge with one OLi3Nb trigonal pyramid.« less
