Title: Materials Data on LaTiNO2 by Materials Project

Abstract

LaTiO2N is Pb(Zr_(1-x)Ti_x)O3-derived structured and crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to three N3- and five O2- atoms. There are a spread of La–N bond distances ranging from 2.53–2.83 Å. There are a spread of La–O bond distances ranging from 2.42–2.84 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to three N3- and five O2- atoms. There are a spread of La–N bond distances ranging from 2.54–2.80 Å. There are a spread of La–O bond distances ranging from 2.42–2.92 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to three N3- and three O2- atoms to form corner-sharing TiN3O3 octahedra. The corner-sharing octahedra tilt angles range from 5–30°. There are a spread of Ti–N bond distances ranging from 1.91–2.03 Å. There are two shorter (2.05 Å) and one longer (2.15 Å) Ti–O bond lengths. In the second Ti4+ site, Ti4+ is bonded to one N3- and five O2- atoms to form corner-sharing TiNO5 octahedra. The corner-sharing octahedra tilt angles range from 5–26°. The Ti–N bond lengthmore » is 1.87 Å. There are a spread of Ti–O bond distances ranging from 2.00–2.13 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a 2-coordinate geometry to two La3+ and two equivalent Ti4+ atoms. In the second N3- site, N3- is bonded in a distorted linear geometry to four La3+ and two Ti4+ atoms. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two La3+ and two equivalent Ti4+ atoms. In the second O2- site, O2- is bonded to two La3+ and two equivalent Ti4+ atoms to form distorted corner-sharing OLa2Ti2 tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two La3+ and two equivalent Ti4+ atoms. In the fourth O2- site, O2- is bonded in a 6-coordinate geometry to four La3+ and two Ti4+ atoms.« less
