Materials Data on ErMn2 by Materials Project
ErMn2 is Hexagonal Laves structured and crystallizes in the monoclinic C2/m 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 four Er and twelve Mn atoms. There are a spread of Er–Er bond distances ranging from 3.07–3.22 Å. There are a spread of Er–Mn bond distances ranging from 2.92–3.11 Å. In the second Er site, Er is bonded in a 12-coordinate geometry to four Er and twelve Mn atoms. There are one shorter (3.21 Å) and two longer (3.22 Å) Er–Er bond lengths. There are a spread of Er–Mn bond distances ranging from 2.92–3.11 Å. There are four inequivalent Mn sites. In the first Mn site, Mn is bonded to six equivalent Er and six Mn atoms to form a mixture of edge, face, and corner-sharing MnEr6Mn6 cuboctahedra. All Mn–Mn bond lengths are 2.54 Å. In the second Mn site, Mn is bonded to six equivalent Er and six Mn atoms to form a mixture of edge, face, and corner-sharing MnEr6Mn6 cuboctahedra. There are two shorter (2.53 Å) and four longer (2.54 Å) Mn–Mn bond lengths. In the third Mn site, Mn is bonded to six Er and six Mn atoms to form a mixture of edge, face, and corner-sharing MnEr6Mn6 cuboctahedra. There are two shorter (2.63 Å) and two longer (2.68 Å) Mn–Mn bond lengths. In the fourth Mn site, Mn is bonded to six Er and six Mn atoms to form a mixture of edge, face, and corner-sharing MnEr6Mn6 cuboctahedra. There are one shorter (2.65 Å) and one longer (2.67 Å) Mn–Mn bond lengths.
