Materials Data on PrAl3Ni2 by Materials Project
PrNi2Al3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Pr is bonded in a 6-coordinate geometry to six equivalent Ni and twelve equivalent Al atoms. All Pr–Ni bond lengths are 3.10 Å. All Pr–Al bond lengths are 3.35 Å. Ni is bonded in a 9-coordinate geometry to three equivalent Pr and six equivalent Al atoms. All Ni–Al bond lengths are 2.54 Å. Al is bonded to four equivalent Pr and four equivalent Ni atoms to form a mixture of distorted face, edge, and corner-sharing AlPr4Ni4 cuboctahedra.
