Materials Data on SmGdB12 by Materials Project
GdSmB12 is Calcium hexaboride-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Gd3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All Gd–B bond lengths are 3.03 Å. Sm3+ is bonded in a 8-coordinate geometry to twenty-four equivalent B+0.50- atoms. All Sm–B bond lengths are 3.03 Å. B+0.50- is bonded in a 1-coordinate geometry to two equivalent Gd3+, two equivalent Sm3+, and five equivalent B+0.50- atoms. There is one shorter (1.64 Å) and four longer (1.75 Å) B–B bond length.
