Title: Materials Data on ErMnSn2 by Materials Project

Abstract

ErMnSn2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 8-coordinate geometry to eight Sn atoms. There are a spread of Er–Sn bond distances ranging from 3.06–3.33 Å. In the second Er site, Er is bonded to seven Sn atoms to form a mixture of distorted edge and corner-sharing ErSn7 pentagonal bipyramids. There are a spread of Er–Sn bond distances ranging from 3.03–3.28 Å. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a 6-coordinate geometry to six Sn atoms. There are a spread of Mn–Sn bond distances ranging from 2.72–2.88 Å. In the second Mn site, Mn is bonded in a 12-coordinate geometry to six Sn atoms. There are a spread of Mn–Sn bond distances ranging from 2.78–2.86 Å. There are five inequivalent Sn sites. In the first Sn site, Sn is bonded in a 2-coordinate geometry to four equivalent Er and two equivalent Mn atoms. In the second Sn site, Sn is bonded in a 2-coordinate geometry to six Er and two equivalent Mn atoms. In the third Sn site, Sn is bonded inmore » a 6-coordinate geometry to two equivalent Er and four Mn atoms. In the fourth Sn site, Sn is bonded in a 9-coordinate geometry to five Er and four Mn atoms. In the fifth Sn site, Sn is bonded in a 7-coordinate geometry to three Er, three Mn, and one Sn atom. The Sn–Sn bond length is 2.92 Å.« less
