Materials Data on HfGaNi by Materials Project

Abstract

HfNiGa crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Hf is bonded in a 11-coordinate geometry to five Ni and six equivalent Ga atoms. There are four shorter (2.70 Å) and one longer (2.75 Å) Hf–Ni bond lengths. There are two shorter (2.87 Å) and four longer (2.96 Å) Hf–Ga bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to three equivalent Hf and six equivalent Ga atoms. All Ni–Ga bond lengths are 2.47 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to six equivalent Hf and three equivalent Ga atoms. All Ni–Ga bond lengths are 2.57 Å. Ga is bonded in a 10-coordinate geometry to six equivalent Hf and four Ni atoms.
