Materials Data on ErMnNi4 by Materials Project

Abstract

ErMnNi4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to four equivalent Mn and twelve equivalent Ni atoms. All Er–Mn bond lengths are 2.98 Å. All Er–Ni bond lengths are 2.86 Å. Mn is bonded in a 12-coordinate geometry to four equivalent Er and twelve equivalent Ni atoms. All Mn–Ni bond lengths are 2.86 Å. Ni is bonded to three equivalent Er, three equivalent Mn, and six equivalent Ni atoms to form a mixture of corner, edge, and face-sharing NiEr3Mn3Ni6 cuboctahedra. There are three shorter (2.42 Å) and three longer (2.45 Å) Ni–Ni bond lengths.
