Materials Data on SnGeO3 by Materials Project
SnGeO3 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are three inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.18–2.51 Å. In the second Sn2+ site, Sn2+ is bonded in a 4-coordinate geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.21–2.33 Å. In the third Sn2+ site, Sn2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.11–2.45 Å. There are three inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.76–1.79 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.73–1.80 Å. In the third Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.76–1.79 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Sn2+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Sn2+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Ge4+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two Sn2+ and one Ge4+ atom. In the sixth O2- site, O2- is bonded in a linear geometry to two equivalent Ge4+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Sn2+ and one Ge4+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Sn2+ and one Ge4+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Ge4+ atoms. In the tenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sn2+ and one Ge4+ atom.
