The crystal structure described by Be3Rh is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded to four equivalent Be(1), four equivalent Be(2), and four equivalent Rh(1) atoms to form distorted BeBe8Rh4 cuboctahedra that share corners with twelve equivalent Be(1)Be8Rh4 cuboctahedra, edges with eight equivalent Be(1)Be8Rh4 cuboctahedra, edges with eight equivalent Rh(1)Be12 cuboctahedra, faces with four equivalent Rh(1)Be12 cuboctahedra, and faces with ten equivalent Be(1)Be8Rh4 cuboctahedra. In the second Be site, Be(2) is bonded in a square co-planar geometry to eight equivalent Be(1) and four equivalent Rh(1) atoms. Rh(1) is bonded to four equivalent Be(2) and eight equivalent Be(1) atoms to form RhBe12 cuboctahedra that share corners with four equivalent Rh(1)Be12 cuboctahedra, edges with eight equivalent Rh(1)Be12 cuboctahedra, edges with sixteen equivalent Be(1)Be8Rh4 cuboctahedra, faces with four equivalent Rh(1)Be12 cuboctahedra, and faces with eight equivalent Be(1)Be8Rh4 cuboctahedra. is represented by the CIF card [CIF]
