TmZn is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tm is bonded in a body-centered cubic geometry to eight equivalent Zn atoms. All Tm–Zn bond lengths are 3.05 Å. Zn is bonded in a body-centered cubic geometry to eight equivalent Tm atoms.
Tm2Zn17 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Tm is bonded in a 10-coordinate geometry to nineteen Zn atoms. There are a spread of Tm–Zn bond distances ranging from 3.09–3.45 Å. There are four inequivalent Zn sites.
