V3Pt crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. V is bonded in a 6-coordinate geometry to two equivalent V and four equivalent Pt atoms. Both V–V bond lengths are 2.41 Å. All V–Pt bond lengths are 2.69 Å. Pt is bonded to twelve equivalent V atoms to form a mixture of edge and face-sharing PtV12 cuboctahedra.
V3Pt is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. V is bonded to eight equivalent V and four equivalent Pt atoms to form distorted VV8Pt4 cuboctahedra that share corners with twelve equivalent VV8Pt4 cuboctahedra, edges with eight equivalent PtV12 cuboctahedra, edges with sixteen equivalent VV8Pt4 cuboctahedra, faces with four equivalent PtV12 cuboctahedra, and faces with fourteen equivalent VV8Pt4 cuboctahedra. All V–V bond lengths are 2.71 Å. All V–Pt bond lengths are 2.71 Å. Pt is bonded to twelve equivalent V atoms to form PtV12 cuboctahedra that share corners with twelve equivalent PtV12 cuboctahedra, edges with twenty-four equivalent VV8Pt4 cuboctahedra, faces with six equivalent PtV12 cuboctahedra, and faces with twelve equivalent VV8Pt4 cuboctahedra.
