Title: Materials Data on Mg(PtO2)3 by Materials Project

Abstract

Mg(PtO2)3 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Mg2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.19 Å) and four longer (2.42 Å) Mg–O bond lengths. There are two inequivalent Pt+3.33+ sites. In the first Pt+3.33+ site, Pt+3.33+ is bonded to six O2- atoms to form a mixture of distorted corner and edge-sharing PtO6 octahedra. The corner-sharing octahedral tilt angles are 60°. There are four shorter (2.05 Å) and two longer (2.07 Å) Pt–O bond lengths. In the second Pt+3.33+ site, Pt+3.33+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Pt–O bond lengths are 1.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one Mg2+ and three Pt+3.33+ atoms to form a mixture of distorted corner and edge-sharing OMgPt3 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Mg2+ and two equivalent Pt+3.33+ atoms to form a mixture of corner and edge-sharing OMg2Pt2 tetrahedra.
