Materials Data on In6Ga2PtO8 by Materials Project

Abstract

PtIn6Ga2O8 is Aluminum carbonitride-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pt2- is bonded to six equivalent In2+ atoms to form PtIn6 octahedra that share corners with twenty-four equivalent OIn3Ga tetrahedra. All Pt–In bond lengths are 2.57 Å. In2+ is bonded in a 5-coordinate geometry to one Pt2- and four equivalent O2- atoms. All In–O bond lengths are 2.30 Å. Ga3+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Ga–O bond lengths are 1.91 Å. O2- is bonded to three equivalent In2+ and one Ga3+ atom to form distorted OIn3Ga tetrahedra that share corners with three equivalent PtIn6 octahedra, corners with six equivalent OIn3Ga tetrahedra, and edges with three equivalent OIn3Ga tetrahedra. The corner-sharing octahedral tilt angles are 62°.
