Materials Data on EuGaSn by Materials Project
EuGaSn crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Eu sites. In the first Eu site, Eu is bonded to six equivalent Sn atoms to form edge-sharing EuSn6 octahedra. All Eu–Sn bond lengths are 3.37 Å. In the second Eu site, Eu is bonded in a 12-coordinate geometry to six equivalent Ga and six equivalent Sn atoms. All Eu–Ga bond lengths are 3.07 Å. All Eu–Sn bond lengths are 3.57 Å. Ga is bonded in a 6-coordinate geometry to three equivalent Eu and three equivalent Sn atoms. All Ga–Sn bond lengths are 2.77 Å. Sn is bonded in a 6-coordinate geometry to six Eu and three equivalent Ga atoms.
