Materials Data on Hf2Ga3 by Materials Project
Hf2Ga3 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Hf is bonded in a 7-coordinate geometry to nine Ga atoms. There are a spread of Hf–Ga bond distances ranging from 2.79–3.16 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 10-coordinate geometry to six equivalent Hf and four equivalent Ga atoms. There are two shorter (2.62 Å) and two longer (2.72 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 10-coordinate geometry to six equivalent Hf and four Ga atoms. Both Ga–Ga bond lengths are 2.75 Å.
