The structure described by NpMn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Np(1) is bonded to twelve equivalent Mn(1) atoms to form NpMn12 cuboctahedra that share corners with twelve equivalent Np(1)Mn12 cuboctahedra, edges with twenty-four equivalent Mn(1)Np4Mn8 cuboctahedra, faces with six equivalent Np(1)Mn12 cuboctahedra, and faces with twelve equivalent Mn(1)Np4Mn8 cuboctahedra. Mn(1) is bonded to four equivalent Np(1) and eight equivalent Mn(1) atoms to form MnNp4Mn8 cuboctahedra that share corners with twelve equivalent Mn(1)Np4Mn8 cuboctahedra, edges with eight equivalent Np(1)Mn12 cuboctahedra, edges with sixteen equivalent Mn(1)Np4Mn8 cuboctahedra, faces with four equivalent Np(1)Mn12 cuboctahedra, and faces with fourteen equivalent Mn(1)Np4Mn8 cuboctahedra. is represented by the CIF file [CIF]
