Title: Materials Data on La2Ti3CuO10 by Materials Project

Abstract

La2Ti3CuO10 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. La3+ is bonded to twelve O2- atoms to form distorted LaO12 cuboctahedra that share corners with eight equivalent LaO12 cuboctahedra, faces with five equivalent LaO12 cuboctahedra, and faces with four equivalent TiO6 octahedra. There are a spread of La–O bond distances ranging from 2.51–2.92 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ti–O bond distances ranging from 1.81–2.32 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent TiO6 octahedra and faces with eight equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is four shorter (1.92 Å) and two longer (1.95 Å) Ti–O bond length. Cu2+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Cu–O bond lengths are 2.01 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+ and two equivalent Cu2+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometrymore » to two equivalent La3+ and two equivalent Ti4+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent La3+ and two equivalent Ti4+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent La3+ and two Ti4+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to four equivalent La3+ and two equivalent Ti4+ atoms.« less
