Materials Data on Mg2VB2Ir5 by Materials Project
Abstract
Mg2VIr5B2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a 11-coordinate geometry to two equivalent Mg, ten Ir, and three B atoms. Both Mg–Mg bond lengths are 2.92 Å. There are a spread of Mg–Ir bond distances ranging from 2.78–2.97 Å. There are one shorter (2.69 Å) and two longer (2.89 Å) Mg–B bond lengths. In the second Mg site, Mg is bonded in a 11-coordinate geometry to two equivalent Mg, ten Ir, and three B atoms. Both Mg–Mg bond lengths are 2.92 Å. There are a spread of Mg–Ir bond distances ranging from 2.78–2.97 Å. There are one shorter (2.69 Å) and two longer (2.89 Å) Mg–B bond lengths. V is bonded in a body-centered cubic geometry to eight equivalent Ir atoms. All V–Ir bond lengths are 2.60 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a distorted body-centered cubic geometry to four equivalent Mg and four equivalent B atoms. All Ir–B bond lengths are 2.22 Å. In the second Ir site, Ir is bonded in a 8-coordinate geometry to four Mg, twomore »
