Title: Materials Data on Li4Ti4Mn5O18 by Materials Project

Abstract

Li4Ti4Mn5O18 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.10–2.59 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 2.16–2.76 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent MnO6 octahedra and edges with four TiO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Ti–O bond distances ranging from 1.92–2.09 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent MnO5 square pyramids and edges with four TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.92–2.04 Å. There are three inequivalent Mn+3.20+ sites. In the first Mn+3.20+ site, Mn+3.20+ is bonded to six O2- atoms to form edge-sharing MnO6 octahedra. All Mn–O bond lengths aremore » 1.95 Å. In the second Mn+3.20+ site, Mn+3.20+ is bonded to five O2- atoms to form MnO5 square pyramids that share corners with two equivalent MnO6 octahedra, corners with four equivalent TiO6 octahedra, and edges with two equivalent MnO5 square pyramids. The corner-sharing octahedra tilt angles range from 50–66°. There are a spread of Mn–O bond distances ranging from 1.95–2.16 Å. In the third Mn+3.20+ site, Mn+3.20+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with two equivalent MnO5 square pyramids, and edges with four MnO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Mn–O bond distances ranging from 1.96–2.26 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+ and three Mn+3.20+ atoms to form a mixture of corner and edge-sharing OLi2Mn3 square pyramids. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti4+ and two equivalent Mn+3.20+ atoms. In the third O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Ti4+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to two Li1+, one Ti4+, and two equivalent Mn+3.20+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Mn+3.20+ atoms. In the sixth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li1+ and two equivalent Ti4+ atoms. In the seventh O2- site, O2- is bonded to two equivalent Li1+ and three Ti4+ atoms to form distorted OLi2Ti3 trigonal bipyramids that share corners with two equivalent OLi2Mn3 trigonal bipyramids and edges with three OLi2Ti3 trigonal bipyramids. In the eighth O2- site, O2- is bonded to two equivalent Li1+ and three Mn+3.20+ atoms to form distorted OLi2Mn3 trigonal bipyramids that share a cornercorner with one OLi2Mn3 square pyramid, corners with two equivalent OLi2Ti3 trigonal bipyramids, and edges with three OLi2Ti3 trigonal bipyramids. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, two equivalent Ti4+, and one Mn+3.20+ atom.« less
