Materials Data on TmSi2 by Materials Project
TmSi2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Tm is bonded to twelve equivalent Si atoms to form a mixture of edge and face-sharing TmSi12 cuboctahedra. All Tm–Si bond lengths are 3.05 Å. Si is bonded in a 9-coordinate geometry to six equivalent Tm and three equivalent Si atoms. All Si–Si bond lengths are 2.36 Å.
