Materials Data on TmAlRh by Materials Project
TmRhAl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm is bonded in a 5-coordinate geometry to five equivalent Rh atoms. There are a spread of Tm–Rh bond distances ranging from 2.86–2.95 Å. Rh is bonded in a 9-coordinate geometry to five equivalent Tm and four equivalent Al atoms. There are a spread of Rh–Al bond distances ranging from 2.59–2.67 Å. Al is bonded to four equivalent Rh atoms to form a mixture of distorted edge and corner-sharing AlRh4 tetrahedra.
