Materials Data on EuTmB12 by Materials Project
TmEuB12 is Calcium hexaboride-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Tm3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All Tm–B bond lengths are 3.02 Å. Eu3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All Eu–B bond lengths are 3.02 Å. B+0.50- is bonded in a 1-coordinate geometry to two equivalent Tm3+, two equivalent Eu3+, and five equivalent B+0.50- atoms. There is one shorter (1.64 Å) and four longer (1.75 Å) B–B bond length.
