Materials Data on CoIr by Materials Project

Abstract

IrCo crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ir is bonded to six equivalent Ir and six equivalent Co atoms to form distorted IrCo6Ir6 cuboctahedra that share corners with eighteen equivalent IrCo6Ir6 cuboctahedra, edges with six equivalent IrCo6Ir6 cuboctahedra, edges with twelve equivalent CoCo6Ir6 cuboctahedra, faces with eight equivalent IrCo6Ir6 cuboctahedra, and faces with twelve equivalent CoCo6Ir6 cuboctahedra. All Ir–Ir bond lengths are 2.67 Å. All Ir–Co bond lengths are 2.57 Å.
