Materials Data on Cr2B2Ir by Materials Project
Abstract
Cr2IrB2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are three inequivalent Cr sites. In the first Cr site, Cr is bonded in a 4-coordinate geometry to five B atoms. There are a spread of Cr–B bond distances ranging from 2.14–2.56 Å. In the second Cr site, Cr is bonded in a 4-coordinate geometry to six B atoms. There are four shorter (2.20 Å) and two longer (2.59 Å) Cr–B bond lengths. In the third Cr site, Cr is bonded in a 8-coordinate geometry to eight B atoms. All Cr–B bond lengths are 2.18 Å. Ir is bonded in a 3-coordinate geometry to three B atoms. There are two shorter (2.14 Å) and one longer (2.30 Å) Ir–B bond lengths. There are two inequivalent B sites. In the first B site, B is bonded in a 9-coordinate geometry to six Cr, two equivalent Ir, and one B atom. The B–B bond length is 1.78 Å. In the second B site, B is bonded in a 9-coordinate geometry to six Cr, one Ir, and two B atoms. The B–B bond length is 1.84 Å.
