Pr5(PtIn2)2 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 2-coordinate geometry to two equivalent Pt(1), two equivalent In(1), and four equivalent In(2) atoms. In the second Pr site, Pr(2) is bonded in a 10-coordinate geometry to four equivalent Pt(1), two equivalent In(2), and four equivalent In(1) atoms. In the third Pr site, Pr(3) is bonded in a distorted body-centered cubic geometry to four equivalent In(1) and four equivalent In(2) atoms. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Pr(1), four equivalent Pr(2), one In(1), and one In(2) atom. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), two equivalent Pr(3), four equivalent Pr(2), one Pt(1), and one In(2) atom. In the second In site, In(2) is bonded in a 10-coordinate geometry to two equivalent Pr(2), two equivalent Pr(3), four equivalent Pr(1), one Pt(1), and one In(1) atom.
