The material structure described by Sm2MnGa6 crystallizes in the cubic Fm-3m space group. Sm(1) is bonded to twelve equivalent Ga(1) atoms to form SmGa12 cuboctahedra that share corners with twelve equivalent Sm(1)Ga12 cuboctahedra, faces with six equivalent Sm(1)Ga12 cuboctahedra, and faces with four equivalent Mn(1)Ga6 octahedra. Mn(1) is bonded to six equivalent Ga(1) atoms to form MnGa6 octahedra that share faces with eight equivalent Sm(1)Ga12 cuboctahedra. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Mn(1), and four equivalent Ga(1) atoms. is represented by the CIF file [CIF]
