Title: Materials Data on Mg(SnO2)2 by Materials Project

Abstract

Mg(SnO2)2 is Spinel structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Mg2+ is bonded to four O2- atoms to form MgO4 tetrahedra that share corners with twelve SnO6 octahedra. The corner-sharing octahedra tilt angles range from 48–61°. There are a spread of Mg–O bond distances ranging from 2.02–2.26 Å. There are four inequivalent Sn3+ sites. In the first Sn3+ site, Sn3+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six equivalent MgO4 tetrahedra and edges with six SnO6 octahedra. There are a spread of Sn–O bond distances ranging from 2.08–2.22 Å. In the second Sn3+ site, Sn3+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six equivalent MgO4 tetrahedra and edges with six SnO6 octahedra. There are four shorter (2.40 Å) and two longer (2.45 Å) Sn–O bond lengths. In the third Sn3+ site, Sn3+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six equivalent MgO4 tetrahedra and edges with six SnO6 octahedra. There are two shorter (2.08 Å) and four longer (2.22 Å) Sn–O bond lengths. In the fourth Sn3+ site, Sn3+ is bonded to sixmore » O2- atoms to form SnO6 octahedra that share corners with six equivalent MgO4 tetrahedra and edges with six SnO6 octahedra. There are four shorter (2.43 Å) and two longer (2.46 Å) Sn–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Mg2+ and three Sn3+ atoms. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Mg2+ and three Sn3+ atoms. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Mg2+ and three Sn3+ atoms. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Mg2+ and three Sn3+ atoms.« less
