Materials Data on TbSnPt2 by Materials Project
TbPt2Sn crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tb is bonded in a 8-coordinate geometry to eight equivalent Pt atoms. There are six shorter (3.01 Å) and two longer (3.13 Å) Tb–Pt bond lengths. Pt is bonded in a 7-coordinate geometry to four equivalent Tb and three equivalent Sn atoms. All Pt–Sn bond lengths are 2.76 Å. Sn is bonded to six equivalent Pt atoms to form distorted edge-sharing SnPt6 cuboctahedra.
