Materials Data on PrAl2Ni by Materials Project
PrNiAl2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Pr is bonded in a 1-coordinate geometry to three equivalent Ni and ten equivalent Al atoms. There are one shorter (2.99 Å) and two longer (3.21 Å) Pr–Ni bond lengths. There are a spread of Pr–Al bond distances ranging from 3.18–3.45 Å. Ni is bonded in a 9-coordinate geometry to three equivalent Pr and six equivalent Al atoms. There are two shorter (2.47 Å) and four longer (2.50 Å) Ni–Al bond lengths. Al is bonded in a 3-coordinate geometry to five equivalent Pr and three equivalent Ni atoms.
