Materials Data on Y2In by Materials Project
Y2In crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 6-coordinate geometry to eight Y and six equivalent In atoms. There are two shorter (3.39 Å) and six longer (3.55 Å) Y–Y bond lengths. All Y–In bond lengths are 3.55 Å. In the second Y site, Y is bonded to six equivalent Y and five equivalent In atoms to form a mixture of distorted corner and face-sharing YY6In5 trigonal bipyramids. There are three shorter (3.12 Å) and two longer (3.39 Å) Y–In bond lengths. In is bonded in a 11-coordinate geometry to eleven Y atoms.
