Materials Data on TmAl2 by Materials Project
TmAl2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Tm is bonded in a 12-coordinate geometry to four equivalent Tm and twelve equivalent Al atoms. All Tm–Tm bond lengths are 3.38 Å. All Tm–Al bond lengths are 3.23 Å. Al is bonded to six equivalent Tm and six equivalent Al atoms to form a mixture of edge, face, and corner-sharing AlTm6Al6 cuboctahedra. All Al–Al bond lengths are 2.76 Å.
