Materials Data on PtRh3 by Materials Project

Rh3Pt is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rh is bonded to eight equivalent Rh and four equivalent Pt atoms to form RhPt4Rh8 cuboctahedra that share corners with twelve equivalent RhPt4Rh8 cuboctahedra, edges with eight equivalent PtRh12 cuboctahedra, edges with sixteen equivalent RhPt4Rh8 cuboctahedra, faces with four equivalent PtRh12 cuboctahedra, and faces with fourteen equivalent RhPt4Rh8 cuboctahedra. All Rh–Rh bond lengths are 2.75 Å. All Rh–Pt bond lengths are 2.75 Å. Pt is bonded to twelve equivalent Rh atoms to form PtRh12 cuboctahedra that share corners with twelve equivalent PtRh12 cuboctahedra, edges with twenty-four equivalent RhPt4Rh8 cuboctahedra, faces with six equivalent PtRh12 cuboctahedra, and faces with twelve equivalent RhPt4Rh8 cuboctahedra.

Materials Data on PtRh3 by Materials Project

Rh3Pt is Copper-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Rh sites. In the first Rh site, Rh is bonded to eight Rh and four equivalent Pt atoms to form RhPt4Rh8 cuboctahedra that share corners with twelve equivalent RhPt4Rh8 cuboctahedra, edges with eight equivalent PtRh12 cuboctahedra, edges with sixteen RhPt4Rh8 cuboctahedra, faces with four equivalent PtRh12 cuboctahedra, and faces with fourteen RhPt4Rh8 cuboctahedra. All Rh–Rh bond lengths are 2.74 Å. All Rh–Pt bond lengths are 2.74 Å. In the second Rh site, Rh is bonded to eight equivalent Rh and four equivalent Pt atoms to form RhPt4Rh8 cuboctahedra that share corners with four equivalent RhPt4Rh8 cuboctahedra, corners with eight equivalent PtRh12 cuboctahedra, edges with twenty-four RhPt4Rh8 cuboctahedra, faces with six equivalent PtRh12 cuboctahedra, and faces with twelve RhPt4Rh8 cuboctahedra. All Rh–Pt bond lengths are 2.74 Å. Pt is bonded to twelve Rh atoms to form PtRh12 cuboctahedra that share corners with four equivalent PtRh12 cuboctahedra, corners with eight equivalent RhPt4Rh8 cuboctahedra, edges with eight equivalent PtRh12 cuboctahedra, edges with sixteen equivalent RhPt4Rh8 cuboctahedra, faces with four equivalent PtRh12 cuboctahedra, and faces with fourteen RhPt4Rh8 cuboctahedra.
