Materials Data on SmInIr by Materials Project
SmIrIn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Sm is bonded in a 11-coordinate geometry to five Ir and six equivalent In atoms. There are four shorter (3.06 Å) and one longer (3.09 Å) Sm–Ir bond lengths. There are two shorter (3.27 Å) and four longer (3.38 Å) Sm–In bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 9-coordinate geometry to three equivalent Sm and six equivalent In atoms. All Ir–In bond lengths are 2.79 Å. In the second Ir site, Ir is bonded in a 9-coordinate geometry to six equivalent Sm and three equivalent In atoms. All Ir–In bond lengths are 2.88 Å. In is bonded in a 10-coordinate geometry to six equivalent Sm and four Ir atoms.
