The material structure described by Mg3Mn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to eight equivalent Mg(1) and four equivalent Mn(1) atoms to form MgMg8Mn4 cuboctahedra that share corners with twelve equivalent Mg(1)Mg8Mn4 cuboctahedra, edges with eight equivalent Mn(1)Mg12 cuboctahedra, edges with sixteen equivalent Mg(1)Mg8Mn4 cuboctahedra, faces with four equivalent Mn(1)Mg12 cuboctahedra, and faces with fourteen equivalent Mg(1)Mg8Mn4 cuboctahedra. Mn(1) is bonded to twelve equivalent Mg(1) atoms to form MnMg12 cuboctahedra that share corners with twelve equivalent Mn(1)Mg12 cuboctahedra, edges with twenty-four equivalent Mg(1)Mg8Mn4 cuboctahedra, faces with six equivalent Mn(1)Mg12 cuboctahedra, and faces with twelve equivalent Mg(1)Mg8Mn4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
