Ni3Mn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mn(1) is bonded to twelve equivalent Ni(1) atoms to form MnNi12 cuboctahedra that share corners with twelve equivalent Mn(1)Ni12 cuboctahedra, edges with twenty-four equivalent Ni(1)Mn4Ni8 cuboctahedra, faces with six equivalent Mn(1)Ni12 cuboctahedra, and faces with twelve equivalent Ni(1)Mn4Ni8 cuboctahedra. Ni(1) is bonded to four equivalent Mn(1) and eight equivalent Ni(1) atoms to form NiMn4Ni8 cuboctahedra that share corners with twelve equivalent Ni(1)Mn4Ni8 cuboctahedra, edges with eight equivalent Mn(1)Ni12 cuboctahedra, edges with sixteen equivalent Ni(1)Mn4Ni8 cuboctahedra, faces with four equivalent Mn(1)Ni12 cuboctahedra, and faces with fourteen equivalent Ni(1)Mn4Ni8 cuboctahedra.
