Materials Data on Tb3Ga2 by Materials Project

Tb3Ga2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are three inequivalent Tb sites. In the first Tb site, Tb is bonded in a 4-coordinate geometry to six Ga atoms. There are a spread of Tb–Ga bond distances ranging from 2.93–3.72 Å. In the second Tb site, Tb is bonded in a 5-coordinate geometry to five Ga atoms. There are a spread of Tb–Ga bond distances ranging from 3.02–3.55 Å. In the third Tb site, Tb is bonded in a 6-coordinate geometry to six Ga atoms. There are a spread of Tb–Ga bond distances ranging from 2.99–3.33 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 8-coordinate geometry to eight equivalent Tb atoms. In the second Ga site, Ga is bonded in a body-centered cubic geometry to eight equivalent Tb atoms. In the third Ga site, Ga is bonded in a 9-coordinate geometry to nine Tb atoms. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to nine Tb and one Ga atom. The Ga–Ga bond length is 2.80 Å.
