Materials Data on U(SiRh)2 by Materials Project
URh2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. U is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All U–Rh bond lengths are 3.21 Å. All U–Si bond lengths are 3.06 Å. Rh is bonded to four equivalent U and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing RhU4Si4 tetrahedra. All Rh–Si bond lengths are 2.42 Å. Si is bonded in a 9-coordinate geometry to four equivalent U, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.31 Å.
