Materials Data on Er2MnGa3 by Materials Project

Abstract

Er2MnGa3 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 12-coordinate geometry to three equivalent Mn and nine Ga atoms. There are two shorter (3.18 Å) and one longer (3.23 Å) Er–Mn bond lengths. There are a spread of Er–Ga bond distances ranging from 3.04–3.28 Å. In the second Er site, Er is bonded in a 12-coordinate geometry to three equivalent Mn and nine Ga atoms. All Er–Mn bond lengths are 3.09 Å. There are a spread of Er–Ga bond distances ranging from 3.03–3.31 Å. Mn is bonded in a 10-coordinate geometry to six Er and four Ga atoms. There are a spread of Mn–Ga bond distances ranging from 2.54–2.82 Å. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 1-coordinate geometry to six Er, one Mn, and three Ga atoms. There are two shorter (2.60 Å) and one longer (2.88 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 2-coordinate geometry to six Er, two equivalent Mn, and two Ga atoms. The Ga–Ga bond length is 2.65 Å. In the third Ga site, Ga is bonded in a 10-coordinate geometry to six Er, one Mn, and three Ga atoms.
