Materials Data on NpB6 by Materials Project
NpB6 is Calcium hexaboride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Np6+ is bonded in a 1-coordinate geometry to twenty-four equivalent B1- atoms. All Np–B bond lengths are 3.00 Å. B1- is bonded in a 1-coordinate geometry to four equivalent Np6+ and five equivalent B1- atoms. There is one shorter (1.62 Å) and four longer (1.75 Å) B–B bond length.
