Materials Data on Er(SiRh)2 by Materials Project
ErRh2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Er is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All Er–Rh bond lengths are 3.21 Å. All Er–Si bond lengths are 3.11 Å. Rh is bonded to four equivalent Er and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing RhEr4Si4 tetrahedra. All Rh–Si bond lengths are 2.40 Å. Si is bonded in a 9-coordinate geometry to four equivalent Er, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.41 Å.
