Materials Data on LaSmB12 by Materials Project
SmLaB12 is Calcium hexaboride-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Sm3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All Sm–B bond lengths are 3.04 Å. La3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All La–B bond lengths are 3.04 Å. B+0.50- is bonded in a 1-coordinate geometry to two equivalent Sm3+, two equivalent La3+, and five equivalent B+0.50- atoms. There is one shorter (1.65 Å) and four longer (1.76 Å) B–B bond length.
