Materials Data on AgIr by Materials Project

Abstract

IrAg is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ir is bonded to six equivalent Ir and six equivalent Ag atoms to form IrAg6Ir6 cuboctahedra that share corners with eighteen equivalent IrAg6Ir6 cuboctahedra, edges with six equivalent IrAg6Ir6 cuboctahedra, edges with twelve equivalent AgAg6Ir6 cuboctahedra, faces with eight equivalent IrAg6Ir6 cuboctahedra, and faces with twelve equivalent AgAg6Ir6 cuboctahedra. All Ir–Ir bond lengths are 2.76 Å. All Ir–Ag bond lengths are 2.92 Å.
