Materials Data on Tb(SiRh)2 by Materials Project
TbRh2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Tb is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All Tb–Rh bond lengths are 3.23 Å. All Tb–Si bond lengths are 3.13 Å. Rh is bonded to four equivalent Tb and four equivalent Si atoms to form a mixture of distorted edge, corner, and face-sharing RhTb4Si4 tetrahedra. All Rh–Si bond lengths are 2.41 Å. Si is bonded in a 9-coordinate geometry to four equivalent Tb, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.44 Å.
