MnGa crystallizes in the hexagonal P-6m2 space group. Mn(1) is bonded to six equivalent Mn(1) and six equivalent Ga(1) atoms to form distorted MnMn6Ga6 cuboctahedra that share corners with eighteen equivalent Mn(1)Mn6Ga6 cuboctahedra, edges with six equivalent Mn(1)Mn6Ga6 cuboctahedra, edges with twelve equivalent Ga(1)Mn6Ga6 cuboctahedra, faces with eight equivalent Mn(1)Mn6Ga6 cuboctahedra, and faces with twelve equivalent Ga(1)Mn6Ga6 cuboctahedra. Ga(1) is bonded to six equivalent Mn(1) and six equivalent Ga(1) atoms to form distorted GaMn6Ga6 cuboctahedra that share corners with eighteen equivalent Ga(1)Mn6Ga6 cuboctahedra, edges with six equivalent Ga(1)Mn6Ga6 cuboctahedra, edges with twelve equivalent Mn(1)Mn6Ga6 cuboctahedra, faces with eight equivalent Ga(1)Mn6Ga6 cuboctahedra, and faces with twelve equivalent Mn(1)Mn6Ga6 cuboctahedra.
