Materials Data on Tm(GeRh2)2 by Materials Project

Tm(Rh2Ge)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm is bonded in a 2-coordinate geometry to eleven Rh and two equivalent Ge atoms. There are a spread of Tm–Rh bond distances ranging from 2.79–3.21 Å. Both Tm–Ge bond lengths are 3.04 Å. There are four inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to three equivalent Tm and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.45–2.64 Å. In the second Rh site, Rh is bonded in a 5-coordinate geometry to three equivalent Tm, three equivalent Rh, and three Ge atoms. There are one shorter (3.00 Å) and two longer (3.01 Å) Rh–Rh bond lengths. There are one shorter (2.49 Å) and two longer (2.55 Å) Rh–Ge bond lengths. In the third Rh site, Rh is bonded in a 1-coordinate geometry to two equivalent Tm, three equivalent Rh, and four Ge atoms. There are two shorter (2.86 Å) and one longer (2.92 Å) Rh–Rh bond lengths. There are a spread of Rh–Ge bond distances ranging from 2.40–2.66 Å. In the fourth Rh site, Rh is bonded in a 4-coordinate geometry to three equivalent Tm, six Rh, and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.48–2.70 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Tm and seven Rh atoms. In the second Ge site, Ge is bonded in a 8-coordinate geometry to eight Rh atoms.
