Sm5(PtIn2)2 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Sm sites. In the first Sm site, Sm(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 Sm site, Sm(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 Sm site, Sm(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 Sm(1), four equivalent Sm(2), one In(2), and two equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 11-coordinate geometry to two equivalent Sm(1), two equivalent Sm(3), four equivalent Sm(2), two equivalent Pt(1), and one In(2) atom. In the second In site, In(2) is bonded in a 10-coordinate geometry to two equivalent Sm(2), two equivalent Sm(3), four equivalent Sm(1), one Pt(1), and one In(1) atom.
