Materials Data on Ba(GeRh)2 by Materials Project
Ba(RhGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Ge atoms. All Ba–Rh bond lengths are 3.72 Å. All Ba–Ge bond lengths are 3.49 Å. Rh is bonded to four equivalent Ba and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing RhBa4Ge4 tetrahedra. All Rh–Ge bond lengths are 2.46 Å. Ge is bonded in a 8-coordinate geometry to four equivalent Ba and four equivalent Rh atoms.
