PrNiIn4 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 15-coordinate geometry to two equivalent Ni(1), three equivalent In(2), four equivalent In(1), and six equivalent In(3) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), one In(2), and six equivalent In(3) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to four equivalent Pr(1), two equivalent In(3), and four equivalent In(2) atoms. In the second In site, In(2) is bonded in a 2-coordinate geometry to three equivalent Pr(1), one Ni(1), and four equivalent In(1) atoms. In the third In site, In(3) is bonded in a 5-coordinate geometry to three equivalent Pr(1), three equivalent Ni(1), and one In(1) atom.
PrNiIn4 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 15-coordinate geometry to two equivalent Ni(1), three equivalent In(2), four equivalent In(1), and six equivalent In(3) atoms. Both Pr(1)-Ni(1) bond lengths are 3.46 Å. There is one shorter (3.27 Å) and two longer (3.70 Å) Pr(1)-In(2) bond lengths. All Pr(1)-In(1) bond lengths are 3.52 Å. There are four shorter (3.35 Å) and two longer (3.56 Å) Pr(1)-In(3) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), one In(2), and six equivalent In(3) atoms.
