The compound described by Eu2IrGa3 crystallizes in the hexagonal P6_3/mmc space group. Eu(1) is bonded in a 12-coordinate geometry to three equivalent Ir(1) and nine equivalent Ga(1) atoms. Ir(1) is bonded to six equivalent Eu(1) and six equivalent Ga(1) atoms to form IrEu6Ga6 cuboctahedra that share corners with twelve equivalent Ga(1)Eu6Ga4Ir2 cuboctahedra, edges with six equivalent Ir(1)Eu6Ga6 cuboctahedra, faces with two equivalent Ir(1)Eu6Ga6 cuboctahedra, and faces with eighteen equivalent Ga(1)Eu6Ga4Ir2 cuboctahedra. Ga(1) is bonded to six equivalent Eu(1), two equivalent Ir(1), and four equivalent Ga(1) atoms to form distorted GaEu6Ga4Ir2 cuboctahedra that share corners with four equivalent Ir(1)Eu6Ga6 cuboctahedra, corners with fourteen equivalent Ga(1)Eu6Ga4Ir2 cuboctahedra, edges with six equivalent Ga(1)Eu6Ga4Ir2 cuboctahedra, faces with six equivalent Ir(1)Eu6Ga6 cuboctahedra, and faces with twelve equivalent Ga(1)Eu6Ga4Ir2 cuboctahedra. is represented by the CIF card [CIF]
