Materials Data on Th(SiRh)2 by Materials Project
Th(RhSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Th is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All Th–Rh bond lengths are 3.28 Å. All Th–Si bond lengths are 3.17 Å. Rh is bonded to four equivalent Th and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing RhTh4Si4 tetrahedra. All Rh–Si bond lengths are 2.44 Å. Si is bonded in a 9-coordinate geometry to four equivalent Th, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.46 Å.
