Materials Data on Tm(SiPt)2 by Materials Project

Tm(PtSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Tm is bonded in a 8-coordinate geometry to eight equivalent Pt and eight equivalent Si atoms. All Tm–Pt bond lengths are 3.23 Å. All Tm–Si bond lengths are 3.28 Å. Pt is bonded in a 9-coordinate geometry to four equivalent Tm and four equivalent Si atoms. All Pt–Si bond lengths are 2.40 Å. Si is bonded to four equivalent Tm and four equivalent Pt atoms to form a mixture of distorted face, edge, and corner-sharing SiTm4Pt4 tetrahedra.
