Title: Materials Data on Y4AlSiNO8 by Materials Project

Abstract

Y4SiAlO8N crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a 7-coordinate geometry to one N3- and six O2- atoms. The Y–N bond length is 2.38 Å. There are a spread of Y–O bond distances ranging from 2.28–2.82 Å. In the second Y3+ site, Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.25–2.83 Å. In the third Y3+ site, Y3+ is bonded to six O2- atoms to form YO6 octahedra that share corners with two equivalent SiNO3 tetrahedra and corners with three equivalent AlNO3 tetrahedra. There are a spread of Y–O bond distances ranging from 2.24–2.40 Å. In the fourth Y3+ site, Y3+ is bonded in a 7-coordinate geometry to one N3- and six O2- atoms. The Y–N bond length is 2.38 Å. There are a spread of Y–O bond distances ranging from 2.25–2.80 Å. Al3+ is bonded to one N3- and three O2- atoms to form AlNO3 tetrahedra that share corners with three equivalent YO6 octahedra and a cornercorner with one SiNO3 tetrahedra. The corner-sharing octahedra tilt angles rangemore » from 48–63°. The Al–N bond length is 1.82 Å. There are a spread of Al–O bond distances ranging from 1.76–1.80 Å. Si4+ is bonded to one N3- and three O2- atoms to form SiNO3 tetrahedra that share corners with two equivalent YO6 octahedra and a cornercorner with one AlNO3 tetrahedra. The corner-sharing octahedra tilt angles range from 29–52°. The Si–N bond length is 1.68 Å. There is one shorter (1.65 Å) and two longer (1.67 Å) Si–O bond length. N3- is bonded in a 4-coordinate geometry to two Y3+, one Al3+, and one Si4+ atom. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Y3+ and one Si4+ atom. In the second O2- site, O2- is bonded to three Y3+ and one Al3+ atom to form distorted corner-sharing OY3Al tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Y3+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Y3+ and one Al3+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Y3+ and one Si4+ atom. In the sixth O2- site, O2- is bonded to four Y3+ atoms to form OY4 tetrahedra that share corners with four OY3Al tetrahedra and edges with two OY4 tetrahedra. In the seventh O2- site, O2- is bonded to four Y3+ atoms to form OY4 tetrahedra that share corners with five OY3Al tetrahedra and edges with two OY4 tetrahedra. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to three Y3+ and one Al3+ atom.« less
