URh2Si2 crystallizes in the tetragonal I4/mmm space group. U(1) is bonded in a 16-coordinate geometry to eight equivalent Rh(1) and eight equivalent Si(1) atoms. Rh(1) is bonded to four equivalent U(1) and four equivalent Si(1) atoms to form a mixture of distorted corner, face, and edge-sharing RhU4Si4 tetrahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent U(1), four equivalent Rh(1), and one Si(1) atom.
