The crystal structure described by Tm5Pt4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 6-coordinate geometry to one Pt(3), two equivalent Pt(2), and three equivalent Pt(1) atoms. In the second Tm site, Tm(2) is bonded in a 7-coordinate geometry to one Pt(2), two equivalent Pt(3), and four equivalent Pt(1) atoms. In the third Tm site, Tm(3) is bonded to two equivalent Pt(1), two equivalent Pt(2), and two equivalent Pt(3) atoms to form distorted corner-sharing TmPt6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(3), four equivalent Tm(2), and one Pt(2) atom. In the second Pt site, Pt(1) is bonded in a 8-coordinate geometry to one Tm(3), three equivalent Tm(1), and four equivalent Tm(2) atoms. In the third Pt site, Pt(2) is bonded in a 9-coordinate geometry to two equivalent Tm(2), two equivalent Tm(3), four equivalent Tm(1), and one Pt(3) atom. is represented by the CIF file [CIF]
