Materials Data on DyMnGa by Materials Project

Abstract

DyMnGa crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 11-coordinate geometry to six Mn and five Ga atoms. There are a spread of Dy–Mn bond distances ranging from 2.94–3.26 Å. There are a spread of Dy–Ga bond distances ranging from 2.94–3.20 Å. In the second Dy site, Dy is bonded in a 11-coordinate geometry to six Mn and five Ga atoms. There are four shorter (2.91 Å) and two longer (3.13 Å) Dy–Mn bond lengths. There are one shorter (3.04 Å) and four longer (3.33 Å) Dy–Ga bond lengths. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a 9-coordinate geometry to six Dy, one Mn, and two equivalent Ga atoms. The Mn–Mn bond length is 2.78 Å. Both Mn–Ga bond lengths are 2.73 Å. In the second Mn site, Mn is bonded in a 12-coordinate geometry to six Dy, two equivalent Mn, and four Ga atoms. There are two shorter (2.59 Å) and two longer (3.04 Å) Mn–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to three Dy, two equivalent Mn, and four equivalent Ga atoms. All Ga–Ga bond lengths are 2.72 Å. In the second Ga site, Ga is bonded in a 11-coordinate geometry to six Dy, three Mn, and two equivalent Ga atoms.
