Materials Data on NdEuB12 by Materials Project
EuNdB12 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. Nd3+ is bonded in a 1-coordinate geometry to twenty-four equivalent B+0.50- atoms. All Nd–B bond lengths are 3.05 Å. B+0.50- is bonded in a 1-coordinate geometry to two equivalent Eu3+, two equivalent Nd3+, and five equivalent B+0.50- atoms. There is one shorter (1.66 Å) and four longer (1.76 Å) B–B bond length.
