PrNiSn crystallizes in the hexagonal P-62m space group. Pr(1) is bonded in a 11-coordinate geometry to one Ni(2), four equivalent Ni(1), and six equivalent Sn(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Sn(1) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
PrNiSn crystallizes in the hexagonal P-62m space group. Pr(1) is bonded in a 11-coordinate geometry to one Ni(2), four equivalent Ni(1), and six equivalent Sn(1) atoms. The Pr(1)-Ni(2) bond length is 3.07 Å. All Pr(1)-Ni(1) bond lengths are 3.02 Å. There are two shorter (3.23 Å) and four longer (3.36 Å) Pr(1)-Sn(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Sn(1) atoms. All Ni(1)-Sn(1) bond lengths are 2.85 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Sn(1) atoms. All Ni(2)-Sn(1) bond lengths are 2.74 Å.
