Pr3In5 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 9-coordinate geometry to one In(1), four equivalent In(2), and four equivalent In(3) atoms. In the second Pr site, Pr(2) is bonded in a 10-coordinate geometry to two equivalent In(1), four equivalent In(2), and four equivalent In(3) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to one Pr(1), four equivalent Pr(2), and two equivalent In(2) atoms. In the second In site, In(2) is bonded in a 10-coordinate geometry to two equivalent Pr(1), four equivalent Pr(2), one In(1), one In(2), and two equivalent In(3) atoms. In the third In site, In(3) is bonded in a 3-coordinate geometry to two equivalent Pr(1), four equivalent Pr(2), and two equivalent In(2) atoms.

In the first Pr site, Pr(1) is bonded in a 9-coordinate geometry to one In(1), four equivalent In(2), and four equivalent In(3) atoms. The Pr(1)-In(1) bond length is 3.19 Å. There are two shorter (3.22 Å) and two longer (3.43 Å) Pr(1)-In(2) bond lengths. There are two shorter (3.25 Å) and two longer (3.59 Å) Pr(1)-In(3) bond lengths. In the second Pr site, Pr(2) is bonded in a 10-coordinate geometry to two equivalent In(1), four equivalent In(2), and four equivalent In(3) atoms. Both Pr(2)-In(1) bond lengths are 3.36 Å. There are two shorter (3.36 Å) and two longer (3.48 Å) Pr(2)-In(2) bond lengths. There are two shorter (3.30 Å) and two longer (3.59 Å) Pr(2)-In(3) bond lengths.
