Materials Data on HfGaRh by Materials Project

Abstract

HfRhGa crystallizes in the trigonal P31m space group. The structure is three-dimensional. Hf is bonded in a 11-coordinate geometry to five Rh and six equivalent Ga atoms. There are four shorter (2.79 Å) and one longer (2.86 Å) Hf–Rh bond lengths. There are a spread of Hf–Ga bond distances ranging from 2.94–3.03 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 9-coordinate geometry to three equivalent Hf and six equivalent Ga atoms. There are three shorter (2.59 Å) and three longer (2.60 Å) Rh–Ga bond lengths. In the second Rh site, Rh is bonded in a 9-coordinate geometry to six equivalent Hf and three equivalent Ga atoms. All Rh–Ga bond lengths are 2.68 Å. Ga is bonded in a 10-coordinate geometry to six equivalent Hf and four Rh atoms.
