Materials Data on Sm(BIr)2 by Materials Project

Abstract

Sm(IrB)2 is alpha Pu-derived structured and crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Sm is bonded in a 2-coordinate geometry to eight equivalent Ir and six equivalent B atoms. There are four shorter (3.08 Å) and four longer (3.27 Å) Sm–Ir bond lengths. There are two shorter (3.02 Å) and four longer (3.15 Å) Sm–B bond lengths. Ir is bonded in a 4-coordinate geometry to four equivalent Sm 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 three equivalent Sm and four equivalent Ir atoms.
