Pr5Sn3 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of two Pr5Sn3 clusters. In one of the Pr5Sn3 clusters, there are five inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a single-bond geometry to one Sn(6) atom. The Pr(1)-Sn(6) bond length is 2.12 Å. In the second Pr site, Pr(6) is bonded in a distorted single-bond geometry to one Sn(6) atom. The Pr(6)-Sn(6) bond length is 2.67 Å. In the third Pr site, Pr(8) is bonded in a single-bond geometry to one Pr(9) atom. The Pr(8)-Pr(9) bond length is 0.60 Å. In the fourth Pr site, Pr(9) is bonded in a 3-coordinate geometry to one Pr(8), one Sn(5), and one Sn(6) atom. The Pr(9)-Sn(5) bond length is 1.57 Å. The Pr(9)-Sn(6) bond length is 2.08 Å. In the fifth Pr site, Pr(10) is bonded in a 1-coordinate geometry to one Sn(4) atom. The Pr(10)-Sn(4) bond length is 3.05 Å. There are three inequivalent Sn sites. In the first Sn site, Sn(4) is bonded in a distorted linear geometry to one Pr(10) and one Sn(6) atom. The Sn(4)-Sn(6) bond length is 1.95 Å. In the second Sn site, Sn(5) is bonded in a single-bond geometry to one Pr(9) atom. In the third Sn site, Sn(6) is bonded in a 2-coordinate geometry to one Pr(1), one Pr(6), one Pr(9), and one Sn(4) atom. In one of the Pr5Sn3 clusters, there are five inequivalent Pr sites. In the first Pr site, Pr(2) is bonded in a 1-coordinate geometry to one Sn(3) atom. The Pr(2)-Sn(3) bond length is 2.67 Å. In the second Pr site, Pr(3) is bonded in a 3-coordinate geometry to one Pr(4), one Sn(1), and one Sn(3) atom. The Pr(3)-Pr(4) bond length is 2.20 Å. The Pr(3)-Sn(1) bond length is 2.29 Å. The Pr(3)-Sn(3) bond length is 2.57 Å. In the third Pr site, Pr(4) is bonded in a single-bond geometry to one Pr(3) and one Sn(2) atom. The Pr(4)-Sn(2) bond length is 0.98 Å. In the fourth Pr site, Pr(5) is bonded in a distorted single-bond geometry to one Sn(1) and one Sn(3) atom. The Pr(5)-Sn(1) bond length is 1.80 Å. The Pr(5)-Sn(3) bond length is 2.15 Å. In the fifth Pr site, Pr(7) is bonded in a distorted single-bond geometry to one Sn(3) atom. The Pr(7)-Sn(3) bond length is 2.67 Å. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 3-coordinate geometry to one Pr(3), one Pr(5), and one Sn(3) atom. The Sn(1)-Sn(3) bond length is 1.64 Å. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one Pr(4) atom. In the third Sn site, Sn(3) is bonded in a 5-coordinate geometry to one Pr(2), one Pr(3), one Pr(5), one Pr(7), and one Sn(1) atom.
