The structure described by Be3Mn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Be(1) is bonded to eight equivalent Be(1) and four equivalent Mn(1) atoms to form BeMn4Be8 cuboctahedra that share corners with twelve equivalent Be(1)Mn4Be8 cuboctahedra, edges with eight equivalent Mn(1)Be12 cuboctahedra, edges with sixteen equivalent Be(1)Mn4Be8 cuboctahedra, faces with four equivalent Mn(1)Be12 cuboctahedra, and faces with fourteen equivalent Be(1)Mn4Be8 cuboctahedra. Mn(1) is bonded to twelve equivalent Be(1) atoms to form MnBe12 cuboctahedra that share corners with twelve equivalent Mn(1)Be12 cuboctahedra, edges with twenty-four equivalent Be(1)Mn4Be8 cuboctahedra, faces with six equivalent Mn(1)Be12 cuboctahedra, and faces with twelve equivalent Be(1)Mn4Be8 cuboctahedra. is represented by the CIF file [CIF]
