The compound described by Eu2GaAl3 is Cubic Laves-derived structured and crystallizes in the trigonal R-3m space group. Eu(1) is bonded in a 12-coordinate geometry to three equivalent Ga(1) and nine equivalent Al(1) atoms. Ga(1) is bonded to six equivalent Eu(1) and six equivalent Al(1) atoms to form GaEu6Al6 cuboctahedra that share corners with six equivalent Ga(1)Eu6Al6 cuboctahedra, corners with twelve equivalent Al(1)Eu6Al4Ga2 cuboctahedra, edges with six equivalent Ga(1)Eu6Al6 cuboctahedra, and faces with eighteen equivalent Al(1)Eu6Al4Ga2 cuboctahedra. Al(1) is bonded to six equivalent Eu(1), two equivalent Ga(1), and four equivalent Al(1) atoms to form AlEu6Al4Ga2 cuboctahedra that share corners with four equivalent Ga(1)Eu6Al6 cuboctahedra, corners with fourteen equivalent Al(1)Eu6Al4Ga2 cuboctahedra, edges with six equivalent Al(1)Eu6Al4Ga2 cuboctahedra, faces with six equivalent Ga(1)Eu6Al6 cuboctahedra, and faces with twelve equivalent Al(1)Eu6Al4Ga2 cuboctahedra. is represented by the CIF card [CIF]
