Materials Data on Nd(BIr)4 by Materials Project

Nd(IrB)4 is alpha Pu-derived structured and crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. Nd is bonded in a 4-coordinate geometry to four equivalent B atoms. All Nd–B bond lengths are 2.93 Å. Ir is bonded in a 4-coordinate geometry to four equivalent B atoms. There are a spread of Ir–B bond distances ranging from 2.11–2.17 Å. B is bonded in a 6-coordinate geometry to one Nd, four equivalent Ir, and one B atom. The B–B bond length is 1.86 Å.
