Tb5(PtIn2)2 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1), two equivalent In(1), and four equivalent In(2) atoms. In the second Tb site, Tb(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 Tb site, Tb(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 9-coordinate geometry to two equivalent Tb(1), four equivalent Tb(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 Tb(1), two equivalent Tb(3), four equivalent Tb(2), two equivalent Pt(1), and one In(2) atom. In the second In site, In(2) is bonded in a 9-coordinate geometry to two equivalent Tb(2), two equivalent Tb(3), four equivalent Tb(1), one Pt(1), and one In(1) atom.
