Materials Data on Gd(SiRh)2 by Materials Project

GdRh2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Gd is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All Gd–Rh bond lengths are 3.24 Å. All Gd–Si bond lengths are 3.14 Å. Rh is bonded to four equivalent Gd and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing RhGd4Si4 tetrahedra. All Rh–Si bond lengths are 2.41 Å. Si is bonded in a 9-coordinate geometry to four equivalent Gd, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.47 Å.
