Materials Data on Ir3Rh by Materials Project

Abstract

Ir3Rh is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ir is bonded to eight equivalent Ir and four equivalent Rh atoms to form IrIr8Rh4 cuboctahedra that share corners with twelve equivalent IrIr8Rh4 cuboctahedra, edges with eight equivalent RhIr12 cuboctahedra, edges with sixteen equivalent IrIr8Rh4 cuboctahedra, faces with four equivalent RhIr12 cuboctahedra, and faces with fourteen equivalent IrIr8Rh4 cuboctahedra. All Ir–Ir bond lengths are 2.74 Å. All Ir–Rh bond lengths are 2.74 Å. Rh is bonded to twelve equivalent Ir atoms to form RhIr12 cuboctahedra that share corners with twelve equivalent RhIr12 cuboctahedra, edges with twenty-four equivalent IrIr8Rh4 cuboctahedra, faces with six equivalent RhIr12 cuboctahedra, and faces with twelve equivalent IrIr8Rh4 cuboctahedra.
