Materials Data on PrAlRh by Materials Project

PrRhAl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Pr is bonded in a 5-coordinate geometry to five equivalent Rh atoms. There are a spread of Pr–Rh bond distances ranging from 2.96–3.13 Å. Rh is bonded in a 9-coordinate geometry to five equivalent Pr and four equivalent Al atoms. There are a spread of Rh–Al bond distances ranging from 2.61–2.81 Å. Al is bonded to four equivalent Rh atoms to form a mixture of distorted edge and corner-sharing AlRh4 tetrahedra.
