TmPt2Sn crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) and six equivalent Sn(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to three equivalent Tm(1), one Pt(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 14-coordinate geometry to six equivalent Tm(1) and eight equivalent Pt(1) atoms.
TmPt2Sn crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) and six equivalent Sn(1) atoms. All Tm(1)-Pt(1) bond lengths are 2.84 Å. All Tm(1)-Sn(1) bond lengths are 3.46 Å. Pt(1) is bonded in a 8-coordinate geometry to three equivalent Tm(1), one Pt(1), and four equivalent Sn(1) atoms. The Pt(1)-Pt(1) bond length is 2.71 Å. There is one shorter (2.87 Å) and three longer (3.05 Å) Pt(1)-Sn(1) bond lengths. Sn(1) is bonded in a 14-coordinate geometry to six equivalent Tm(1) and eight equivalent Pt(1) atoms.
