Materials Data on CeSiBIr3 by Materials Project

Abstract

CeIr3BSi crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to twelve equivalent Ir, three equivalent B, and three equivalent Si atoms. All Ce–Ir bond lengths are 3.27 Å. All Ce–B bond lengths are 3.20 Å. All Ce–Si bond lengths are 3.20 Å. Ir is bonded in a distorted rectangular see-saw-like geometry to four equivalent Ce, two equivalent B, and two equivalent Si atoms. Both Ir–B bond lengths are 2.32 Å. Both Ir–Si bond lengths are 2.41 Å. B is bonded in a 9-coordinate geometry to three equivalent Ce and six equivalent Ir atoms. Si is bonded in a 6-coordinate geometry to three equivalent Ce and six equivalent Ir atoms.
