Materials Data on MoIr3 by Materials Project
Ir3Mo is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mo is bonded to twelve equivalent Ir atoms to form MoIr12 cuboctahedra that share corners with six equivalent MoIr12 cuboctahedra, corners with twelve equivalent IrMo4Ir8 cuboctahedra, edges with eighteen equivalent IrMo4Ir8 cuboctahedra, faces with eight equivalent MoIr12 cuboctahedra, and faces with twelve equivalent IrMo4Ir8 cuboctahedra. There are six shorter (2.73 Å) and six longer (2.77 Å) Mo–Ir bond lengths. Ir is bonded to four equivalent Mo and eight equivalent Ir atoms to form IrMo4Ir8 cuboctahedra that share corners with four equivalent MoIr12 cuboctahedra, corners with fourteen equivalent IrMo4Ir8 cuboctahedra, edges with six equivalent MoIr12 cuboctahedra, edges with twelve equivalent IrMo4Ir8 cuboctahedra, faces with four equivalent MoIr12 cuboctahedra, and faces with sixteen equivalent IrMo4Ir8 cuboctahedra. There are a spread of Ir–Ir bond distances ranging from 2.73–2.78 Å.
