Materials Data on Tb(BIr)4 by Materials Project

Tb(IrB)4 is alpha Pu-derived structured and crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. Tb is bonded in a 4-coordinate geometry to four equivalent B atoms. All Tb–B bond lengths are 2.90 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 2.10–2.18 Å. B is bonded in a 6-coordinate geometry to one Tb, four equivalent Ir, and one B atom. The B–B bond length is 1.84 Å.

Materials Data on Tb(BIr)2 by Materials Project

Tb(IrB)2 is alpha Pu-derived structured and crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Tb is bonded in a 2-coordinate geometry to eight equivalent Ir and ten equivalent B atoms. There are four shorter (3.06 Å) and four longer (3.22 Å) Tb–Ir bond lengths. There are a spread of Tb–B bond distances ranging from 2.99–3.35 Å. Ir is bonded in a 4-coordinate geometry to four equivalent Tb and four equivalent B atoms. There are two shorter (2.09 Å) and two longer (2.18 Å) Ir–B bond lengths. B is bonded in a 4-coordinate geometry to five equivalent Tb and four equivalent Ir atoms.
