Title: Materials Data on SrSi7N10 by Materials Project

Abstract

SrSi7N10 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Sr2+ is bonded in a 2-coordinate geometry to six N3- atoms. There are a spread of Sr–N bond distances ranging from 2.67–3.27 Å. There are seven inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four N3- atoms to form a mixture of corner and edge-sharing SiN4 tetrahedra. There are a spread of Si–N bond distances ranging from 1.68–1.80 Å. In the second Si4+ site, Si4+ is bonded to four N3- atoms to form corner-sharing SiN4 tetrahedra. There is one shorter (1.69 Å) and three longer (1.77 Å) Si–N bond length. In the third Si4+ site, Si4+ is bonded to four N3- atoms to form corner-sharing SiN4 tetrahedra. There is two shorter (1.72 Å) and two longer (1.74 Å) Si–N bond length. In the fourth Si4+ site, Si4+ is bonded to four N3- atoms to form a mixture of corner and edge-sharing SiN4 tetrahedra. There are a spread of Si–N bond distances ranging from 1.67–1.77 Å. In the fifth Si4+ site, Si4+ is bonded to four N3- atoms to form corner-sharing SiN4 tetrahedra. There are a spread of Si–N bond distances ranging from 1.69–1.80 Å.more » In the sixth Si4+ site, Si4+ is bonded to four N3- atoms to form corner-sharing SiN4 tetrahedra. There is one shorter (1.73 Å) and three longer (1.74 Å) Si–N bond length. In the seventh Si4+ site, Si4+ is bonded to four N3- atoms to form corner-sharing SiN4 tetrahedra. There are a spread of Si–N bond distances ranging from 1.71–1.76 Å. There are ten inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to three Si4+ atoms. In the second N3- site, N3- is bonded in a 3-coordinate geometry to one Sr2+ and two Si4+ atoms. In the third N3- site, N3- is bonded in a 4-coordinate geometry to one Sr2+ and three Si4+ atoms. In the fourth N3- site, N3- is bonded in a distorted trigonal planar geometry to one Sr2+ and three Si4+ atoms. In the fifth N3- site, N3- is bonded in a 3-coordinate geometry to one Sr2+ and three Si4+ atoms. In the sixth N3- site, N3- is bonded in a trigonal planar geometry to three Si4+ atoms. In the seventh N3- site, N3- is bonded in a distorted bent 150 degrees geometry to two equivalent Sr2+ and two Si4+ atoms. In the eighth N3- site, N3- is bonded in a trigonal planar geometry to three Si4+ atoms. In the ninth N3- site, N3- is bonded in a trigonal planar geometry to three Si4+ atoms. In the tenth N3- site, N3- is bonded in a trigonal planar geometry to three Si4+ atoms.« less
