Materials Data on SmB2Ir3 by Materials Project
SmIr3B2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Sm is bonded in a 12-coordinate geometry to two equivalent Sm, twelve equivalent Ir, and six equivalent B atoms. Both Sm–Sm bond lengths are 3.15 Å. All Sm–Ir bond lengths are 3.18 Å. All Sm–B bond lengths are 3.18 Å. Ir is bonded in a distorted square co-planar geometry to four equivalent Sm and four equivalent B atoms. All Ir–B bond lengths are 2.24 Å. B is bonded in a 6-coordinate geometry to three equivalent Sm and six equivalent Ir atoms.
