Materials Data on Tm4CdPt by Materials Project

Tm4PtCd crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are three inequivalent Tm sites. In the first Tm site, Tm is bonded in a 3-coordinate geometry to three equivalent Pt and three equivalent Cd atoms. All Tm–Pt bond lengths are 2.82 Å. All Tm–Cd bond lengths are 3.34 Å. In the second Tm site, Tm is bonded in a distorted bent 150 degrees geometry to two equivalent Pt and two equivalent Cd atoms. Both Tm–Pt bond lengths are 2.80 Å. Both Tm–Cd bond lengths are 3.46 Å. In the third Tm site, Tm is bonded in a 4-coordinate geometry to two equivalent Pt and two equivalent Cd atoms. Both Tm–Pt bond lengths are 3.47 Å. Both Tm–Cd bond lengths are 3.21 Å. Pt is bonded in a 6-coordinate geometry to nine Tm atoms. Cd is bonded to nine Tm and three equivalent Cd atoms to form a mixture of distorted face and corner-sharing CdTm9Cd3 cuboctahedra. All Cd–Cd bond lengths are 3.14 Å.
