PrNiAl2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1) and ten equivalent Al(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 3-coordinate geometry to five equivalent Pr(1) and three equivalent Ni(1) atoms.
PrNiAl2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1) and ten equivalent Al(1) atoms. There is one shorter (3.00 Å) and two longer (3.25 Å) Pr(1)-Ni(1) bond lengths. There are a spread of Pr(1)-Al(1) bond distances ranging from 3.23-3.49 Å. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Al(1) atoms. There are two shorter (2.43 Å) and four longer (2.47 Å) Ni(1)-Al(1) bond lengths. Al(1) is bonded in a 3-coordinate geometry to five equivalent Pr(1) and three equivalent Ni(1) atoms.
