Materials Data on Tm(SiRh)2 by Materials Project
Tm(RhSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Tm is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All Tm–Rh bond lengths are 3.20 Å. All Tm–Si bond lengths are 3.11 Å. Rh is bonded to four equivalent Tm and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing RhTm4Si4 tetrahedra. All Rh–Si bond lengths are 2.40 Å. Si is bonded in a 9-coordinate geometry to four equivalent Tm, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.40 Å.
