Materials Data on HoAlRh by Materials Project
HoRhAl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ho is bonded in a 5-coordinate geometry to five equivalent Rh atoms. There are a spread of Ho–Rh bond distances ranging from 2.89–2.99 Å. Rh is bonded in a 9-coordinate geometry to five equivalent Ho and four equivalent Al atoms. There are a spread of Rh–Al bond distances ranging from 2.61–2.68 Å. Al is bonded to four equivalent Rh atoms to form a mixture of distorted corner and edge-sharing AlRh4 tetrahedra.
