Re3Ir is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Re(1) is bonded to eight equivalent Re(1) and four equivalent Ir(1) atoms to form ReRe8Ir4 cuboctahedra that share corners with twelve equivalent Re(1)Re8Ir4 cuboctahedra, edges with eight equivalent Ir(1)Re12 cuboctahedra, edges with sixteen equivalent Re(1)Re8Ir4 cuboctahedra, faces with four equivalent Ir(1)Re12 cuboctahedra, and faces with fourteen equivalent Re(1)Re8Ir4 cuboctahedra. Ir(1) is bonded to twelve equivalent Re(1) atoms to form IrRe12 cuboctahedra that share corners with twelve equivalent Ir(1)Re12 cuboctahedra, edges with twenty-four equivalent Re(1)Re8Ir4 cuboctahedra, faces with six equivalent Ir(1)Re12 cuboctahedra, and faces with twelve equivalent Re(1)Re8Ir4 cuboctahedra.
