TmEuB12 is Calcium hexaboride-derived structured and crystallizes in the tetragonal P4/mmm space group. Tm(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1,2) atoms. Eu(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1,2) atoms. B(1,2) is bonded in a 5-coordinate geometry to two equivalent Tm(1); two equivalent Eu(1); and five equivalent B(1,2) atoms.
TmEuB12 is Calcium hexaboride-derived structured and crystallizes in the tetragonal P4/mmm space group. Tm(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1,2) atoms. All Tm(1)-B(1,2) bond lengths are 3.02 Å. Eu(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1,2) atoms. All Eu(1)-B(1,2) bond lengths are 3.02 Å. B(1,2) is bonded in a 5-coordinate geometry to two equivalent Tm(1); two equivalent Eu(1); and five equivalent B(1,2) atoms. There is one shorter (1.64 Å) and four longer (1.75 Å) B(1,2)-B(1,2) bond lengths.
