Materials Data on Yb(SiRh)2 by Materials Project
YbRh2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb2+ is bonded in a distorted body-centered cubic geometry to eight equivalent Si4- atoms. All Yb–Si bond lengths are 3.16 Å. Rh3+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing RhSi4 tetrahedra. All Rh–Si bond lengths are 2.39 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Yb2+, four equivalent Rh3+, and one Si4- atom. The Si–Si bond length is 2.49 Å.
