Mn3Pt is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mn(1) is bonded to eight equivalent Mn(1) and four equivalent Pt(1) atoms to form distorted MnMn8Pt4 cuboctahedra that share corners with twelve equivalent Mn(1)Mn8Pt4 cuboctahedra, edges with eight equivalent Pt(1)Mn12 cuboctahedra, edges with sixteen equivalent Mn(1)Mn8Pt4 cuboctahedra, faces with four equivalent Pt(1)Mn12 cuboctahedra, and faces with fourteen equivalent Mn(1)Mn8Pt4 cuboctahedra. Pt(1) is bonded to twelve equivalent Mn(1) atoms to form PtMn12 cuboctahedra that share corners with twelve equivalent Pt(1)Mn12 cuboctahedra, edges with twenty-four equivalent Mn(1)Mn8Pt4 cuboctahedra, faces with six equivalent Pt(1)Mn12 cuboctahedra, and faces with twelve equivalent Mn(1)Mn8Pt4 cuboctahedra.
