Materials Data on MgBe4Cu by Materials Project

Abstract

MgBe4Cu is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mg is bonded in a 4-coordinate geometry to twelve equivalent Be and four equivalent Cu atoms. All Mg–Be bond lengths are 2.59 Å. All Mg–Cu bond lengths are 2.71 Å. Be is bonded to three equivalent Mg, six equivalent Be, and three equivalent Cu atoms to form a mixture of edge, face, and corner-sharing BeMg3Be6Cu3 cuboctahedra. There are three shorter (2.18 Å) and three longer (2.23 Å) Be–Be bond lengths. All Be–Cu bond lengths are 2.59 Å. Cu is bonded in a 4-coordinate geometry to four equivalent Mg and twelve equivalent Be atoms.
