Materials Data on TbRh5 by Materials Project
TbRh5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Tb is bonded in a distorted hexagonal planar geometry to eighteen Rh atoms. There are six shorter (3.03 Å) and twelve longer (3.40 Å) Tb–Rh bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 3-coordinate geometry to three equivalent Tb and six equivalent Rh atoms. All Rh–Rh bond lengths are 2.64 Å. In the second Rh site, Rh is bonded to four equivalent Tb and eight Rh atoms to form a mixture of edge, face, and corner-sharing RhTb4Rh8 cuboctahedra. All Rh–Rh bond lengths are 2.63 Å.
