Materials Data on Tb(GeRh)2 by Materials Project

TbRh2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Tb is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Ge atoms. All Tb–Rh bond lengths are 3.33 Å. All Tb–Ge bond lengths are 3.19 Å. Rh is bonded to four equivalent Tb and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing RhTb4Ge4 tetrahedra. All Rh–Ge bond lengths are 2.47 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Tb, four equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.53 Å.

Materials Data on Tb3(GeRh)2 by Materials Project

Tb3(RhGe)2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 9-coordinate geometry to four equivalent Rh and five Ge atoms. There are two shorter (3.04 Å) and two longer (3.08 Å) Tb–Rh bond lengths. There are a spread of Tb–Ge bond distances ranging from 3.03–3.32 Å. In the second Tb site, Tb is bonded in a 7-coordinate geometry to four equivalent Rh and five Ge atoms. There are a spread of Tb–Rh bond distances ranging from 2.92–3.15 Å. There are a spread of Tb–Ge bond distances ranging from 3.01–3.37 Å. Rh is bonded in a 9-coordinate geometry to six Tb and three Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.55–2.62 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Tb and two equivalent Rh atoms. In the second Ge site, Ge is bonded in a 12-coordinate geometry to eight Tb and four equivalent Rh atoms.
