Pt3Ni is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pt(1) is bonded to eight equivalent Pt(1) and four equivalent Ni(1) atoms to form PtNi4Pt8 cuboctahedra that share corners with twelve equivalent Pt(1)Ni4Pt8 cuboctahedra, edges with eight equivalent Ni(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Ni4Pt8 cuboctahedra, faces with four equivalent Ni(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Ni4Pt8 cuboctahedra. Ni(1) is bonded to twelve equivalent Pt(1) atoms to form NiPt12 cuboctahedra that share corners with twelve equivalent Ni(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Ni4Pt8 cuboctahedra, faces with six equivalent Ni(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Ni4Pt8 cuboctahedra.
