Materials Data on VRh3 by Materials Project

Rh3V is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. V is bonded to twelve equivalent Rh atoms to form VRh12 cuboctahedra that share corners with twelve equivalent VRh12 cuboctahedra, edges with twenty-four equivalent RhV4Rh8 cuboctahedra, faces with six equivalent VRh12 cuboctahedra, and faces with twelve equivalent RhV4Rh8 cuboctahedra. All V–Rh bond lengths are 2.70 Å. Rh is bonded to four equivalent V and eight equivalent Rh atoms to form distorted RhV4Rh8 cuboctahedra that share corners with twelve equivalent RhV4Rh8 cuboctahedra, edges with eight equivalent VRh12 cuboctahedra, edges with sixteen equivalent RhV4Rh8 cuboctahedra, faces with four equivalent VRh12 cuboctahedra, and faces with fourteen equivalent RhV4Rh8 cuboctahedra. All Rh–Rh bond lengths are 2.70 Å.

Materials Data on VRh3 by Materials Project

Rh3V is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. V is bonded to twelve equivalent Rh atoms to form VRh12 cuboctahedra that share corners with six equivalent VRh12 cuboctahedra, corners with twelve equivalent RhV4Rh8 cuboctahedra, edges with eighteen equivalent RhV4Rh8 cuboctahedra, faces with eight equivalent VRh12 cuboctahedra, and faces with twelve equivalent RhV4Rh8 cuboctahedra. There are six shorter (2.67 Å) and six longer (2.72 Å) V–Rh bond lengths. Rh is bonded to four equivalent V and eight equivalent Rh atoms to form distorted RhV4Rh8 cuboctahedra that share corners with four equivalent VRh12 cuboctahedra, corners with fourteen equivalent RhV4Rh8 cuboctahedra, edges with six equivalent VRh12 cuboctahedra, edges with twelve equivalent RhV4Rh8 cuboctahedra, faces with four equivalent VRh12 cuboctahedra, and faces with sixteen equivalent RhV4Rh8 cuboctahedra. There are a spread of Rh–Rh bond distances ranging from 2.68–2.73 Å.
