Materials Data on YSiIr2 by Materials Project
Abstract
YIr2Si crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are four inequivalent Y sites. In the first Y site, Y is bonded in a 9-coordinate geometry to one Y and nine equivalent Ir atoms. The Y–Y bond length is 3.20 Å. There are three shorter (3.04 Å) and six longer (3.12 Å) Y–Ir bond lengths. In the second Y site, Y is bonded in a 9-coordinate geometry to one Y and nine equivalent Ir atoms. The Y–Y bond length is 3.20 Å. There are three shorter (3.04 Å) and six longer (3.12 Å) Y–Ir bond lengths. In the third Y site, Y is bonded in a 9-coordinate geometry to one Y and nine equivalent Ir atoms. The Y–Y bond length is 3.20 Å. There are three shorter (3.04 Å) and six longer (3.12 Å) Y–Ir bond lengths. In the fourth Y site, Y is bonded in a 6-coordinate geometry to two Y, twelve equivalent Ir, and six Si atoms. All Y–Ir bond lengths are 3.33 Å. All Y–Si bond lengths are 3.22 Å. Ir is bonded in a 12-coordinate geometry to five Y, four equivalent Ir, and three Si atoms. There are two shorter (2.78 Å)more »

In the first Si site, Si is bonded in a 9-coordinate geometry to three equivalent Y and six equivalent Ir atoms. In the second Si site, Si is bonded in a 9-coordinate geometry to three equivalent Y and six equivalent Ir atoms. In the third Si site, Si is bonded in a distorted cuboctahedral geometry to six equivalent Ir atoms.},
