Materials Data on Pr(BIr)2 by Materials Project
Pr(IrB)2 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Pr is bonded to four equivalent Ir and four equivalent B atoms to form distorted face-sharing PrB4Ir4 hexagonal bipyramids. There are two shorter (3.08 Å) and two longer (3.09 Å) Pr–Ir bond lengths. There are two shorter (2.89 Å) and two longer (2.91 Å) Pr–B bond lengths. Ir is bonded in a 1-coordinate geometry to two equivalent Pr and five equivalent B atoms. There are a spread of Ir–B bond distances ranging from 2.19–2.36 Å. B is bonded in a 8-coordinate geometry to two equivalent Pr, five equivalent Ir, and one B atom. The B–B bond length is 1.82 Å.
