Materials Data on LaEuB12 by Materials Project

EuLaB12 is Calcium hexaboride-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Eu3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All Eu–B bond lengths are 3.05 Å. La3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All La–B bond lengths are 3.05 Å. B+0.50- is bonded in a 1-coordinate geometry to two equivalent Eu3+, two equivalent La3+, and five equivalent B+0.50- atoms. There is one shorter (1.67 Å) and four longer (1.76 Å) B–B bond length.

Materials Data on LaEuB12 by Materials Project

EuLaB12 is Calcium hexaboride-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Eu3+ is bonded in a 1-coordinate geometry to twenty-four B+0.50- atoms. All Eu–B bond lengths are 3.05 Å. La3+ is bonded in a 8-coordinate geometry to twenty-four B+0.50- atoms. All La–B bond lengths are 3.05 Å. There are three inequivalent B+0.50- sites. In the first B+0.50- site, B+0.50- is bonded in a 1-coordinate geometry to two equivalent Eu3+, two equivalent La3+, and five B+0.50- atoms. There is one shorter (1.66 Å) and four longer (1.76 Å) B–B bond length. In the second B+0.50- site, B+0.50- is bonded in a 1-coordinate geometry to four equivalent La3+ and five B+0.50- atoms. The B–B bond length is 1.66 Å. In the third B+0.50- site, B+0.50- is bonded in a 1-coordinate geometry to four equivalent Eu3+ and five B+0.50- atoms. The B–B bond length is 1.66 Å.
