PrNiIn crystallizes in the hexagonal P-62m space group. Pr(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent In(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent In(1) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent In(1) atoms. In(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
PrNiIn crystallizes in the hexagonal P-62m space group. Pr(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent In(1) atoms. The Pr(1)-Ni(1) bond length is 3.18 Å. All Pr(1)-Ni(2) bond lengths are 3.01 Å. There are two shorter (3.23 Å) and four longer (3.38 Å) Pr(1)-In(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent In(1) atoms. All Ni(1)-In(1) bond lengths are 2.70 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent In(1) atoms. All Ni(2)-In(1) bond lengths are 2.93 Å. In(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
