Materials Data on Si6Bi9O26 by Materials Project
Si6Bi9O26 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one BiO6 pentagonal pyramid. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent BiO6 pentagonal pyramids and an edgeedge with one BiO6 pentagonal pyramid. There are a spread of Si–O bond distances ranging from 1.63–1.67 Å. There are five inequivalent Bi+3.11+ sites. In the first Bi+3.11+ site, Bi+3.11+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.34–2.88 Å. In the second Bi+3.11+ site, Bi+3.11+ is bonded to six O2- atoms to form distorted BiO6 pentagonal pyramids that share corners with four equivalent BiO6 pentagonal pyramids, corners with three SiO4 tetrahedra, and an edgeedge with one SiO4 tetrahedra. There are a spread of Bi–O bond distances ranging from 2.30–2.54 Å. In the third Bi+3.11+ site, Bi+3.11+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.29 Å) and three longer (2.62 Å) Bi–O bond lengths. In the fourth Bi+3.11+ site, Bi+3.11+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Bi–O bond distances ranging from 2.30–2.85 Å. In the fifth Bi+3.11+ site, Bi+3.11+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Bi–O bond lengths are 2.18 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Si4+ and two equivalent Bi+3.11+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Si4+ and three Bi+3.11+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Si4+ and two Bi+3.11+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Si4+ and two Bi+3.11+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Si4+ and two Bi+3.11+ atoms. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Si4+ and two Bi+3.11+ atoms. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Bi+3.11+ atoms. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Bi+3.11+ atoms. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to one Si4+ and two Bi+3.11+ atoms. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one Si4+ and two Bi+3.11+ atoms.
