Materials Data on IrOs by Materials Project

Abstract

OsIr is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Os is bonded to six equivalent Os and six equivalent Ir atoms to form OsIr6Os6 cuboctahedra that share corners with eighteen equivalent OsIr6Os6 cuboctahedra, edges with six equivalent OsIr6Os6 cuboctahedra, edges with twelve equivalent IrIr6Os6 cuboctahedra, faces with eight equivalent OsIr6Os6 cuboctahedra, and faces with twelve equivalent IrIr6Os6 cuboctahedra. All Os–Os bond lengths are 2.76 Å. All Os–Ir bond lengths are 2.71 Å. Ir is bonded to six equivalent Os and six equivalent Ir atoms to form IrIr6Os6 cuboctahedra that share corners with eighteen equivalent IrIr6Os6 cuboctahedra, edges with six equivalent IrIr6Os6 cuboctahedra, edges with twelve equivalent OsIr6Os6 cuboctahedra, faces with eight equivalent IrIr6Os6 cuboctahedra, and faces with twelve equivalent OsIr6Os6 cuboctahedra. All Ir–Ir bond lengths are 2.76 Å.
