The crystal structure described by Mn2Cu3Ga is Cubic Laves-derived structured and crystallizes in the trigonal R-3m space group. Mn(1) is bonded in a 16-coordinate geometry to four equivalent Mn(1), nine equivalent Cu(1), and three equivalent Ga(1) atoms. Cu(1) is bonded to six equivalent Mn(1), four equivalent Cu(1), and two equivalent Ga(1) atoms to form CuMn6Ga2Cu4 cuboctahedra that share corners with four equivalent Ga(1)Mn6Cu6 cuboctahedra, corners with fourteen equivalent Cu(1)Mn6Ga2Cu4 cuboctahedra, edges with six equivalent Cu(1)Mn6Ga2Cu4 cuboctahedra, faces with six equivalent Ga(1)Mn6Cu6 cuboctahedra, and faces with twelve equivalent Cu(1)Mn6Ga2Cu4 cuboctahedra. Ga(1) is bonded to six equivalent Mn(1) and six equivalent Cu(1) atoms to form GaMn6Cu6 cuboctahedra that share corners with six equivalent Ga(1)Mn6Cu6 cuboctahedra, corners with twelve equivalent Cu(1)Mn6Ga2Cu4 cuboctahedra, edges with six equivalent Ga(1)Mn6Cu6 cuboctahedra, and faces with eighteen equivalent Cu(1)Mn6Ga2Cu4 cuboctahedra. is represented by the CIF card [CIF]
