Materials Data on PrZnNi by Materials Project
PrNiZn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Pr is bonded in a 11-coordinate geometry to five Ni and six equivalent Zn atoms. There are four shorter (2.92 Å) and one longer (2.99 Å) Pr–Ni bond lengths. There are two shorter (3.22 Å) and four longer (3.24 Å) Pr–Zn bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to three equivalent Pr and six equivalent Zn atoms. All Ni–Zn bond lengths are 2.58 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to six equivalent Pr and three equivalent Zn atoms. All Ni–Zn bond lengths are 2.84 Å. Zn is bonded in a 12-coordinate geometry to six equivalent Pr, four Ni, and two equivalent Zn atoms. Both Zn–Zn bond lengths are 2.92 Å.
