Materials Data on Dy3Ga2 by Materials Project

Abstract

Dy3Ga2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 4-coordinate geometry to six Ga atoms. There are a spread of Dy–Ga bond distances ranging from 2.92–3.71 Å. In the second Dy site, Dy is bonded in a 5-coordinate geometry to five Ga atoms. There are a spread of Dy–Ga bond distances ranging from 3.01–3.53 Å. In the third Dy site, Dy is bonded in a 6-coordinate geometry to six Ga atoms. There are a spread of Dy–Ga bond distances ranging from 2.97–3.32 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 8-coordinate geometry to eight equivalent Dy atoms. In the second Ga site, Ga is bonded in a body-centered cubic geometry to eight equivalent Dy atoms. In the third Ga site, Ga is bonded in a 9-coordinate geometry to nine Dy atoms. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to nine Dy and one Ga atom. The Ga–Ga bond length is 2.80 Å.
