Materials Data on HfMnGa2 by Materials Project
Abstract
HfMnGa2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Hf sites. In the first Hf site, Hf is bonded in a 12-coordinate geometry to four Mn and eight Ga atoms. There are a spread of Hf–Mn bond distances ranging from 3.01–3.13 Å. There are a spread of Hf–Ga bond distances ranging from 2.79–3.03 Å. In the second Hf site, Hf is bonded in a 7-coordinate geometry to seven Ga atoms. There are a spread of Hf–Ga bond distances ranging from 2.78–2.97 Å. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a 12-coordinate geometry to three equivalent Hf and six Ga atoms. There are a spread of Mn–Ga bond distances ranging from 2.44–2.69 Å. In the second Mn site, Mn is bonded in a 12-coordinate geometry to two equivalent Hf and six Ga atoms. There are a spread of Mn–Ga bond distances ranging from 2.48–2.65 Å. There are five inequivalent Ga sites. In the first Ga site, Ga is bonded in a 2-coordinate geometry to five Hf, two equivalent Mn, and four Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.58–2.96 Å. Inmore »
