Title: Materials Data on CeMg6Cu by Materials Project

Abstract

Mg6CeCu crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a distorted single-bond geometry to six Mg, two equivalent Ce, and one Cu atom. There are a spread of Mg–Mg bond distances ranging from 3.06–3.42 Å. There are one shorter (3.44 Å) and one longer (3.57 Å) Mg–Ce bond lengths. The Mg–Cu bond length is 2.82 Å. In the second Mg site, Mg is bonded in a 2-coordinate geometry to six Mg, two equivalent Ce, and two equivalent Cu atoms. There are a spread of Mg–Mg bond distances ranging from 2.96–3.26 Å. Both Mg–Ce bond lengths are 3.26 Å. Both Mg–Cu bond lengths are 2.96 Å. In the third Mg site, Mg is bonded in a 2-coordinate geometry to eight Mg and two equivalent Cu atoms. Both Mg–Mg bond lengths are 3.08 Å. Both Mg–Cu bond lengths are 3.29 Å. In the fourth Mg site, Mg is bonded in a 2-coordinate geometry to eight Mg and two equivalent Ce atoms. Both Mg–Ce bond lengths are 3.18 Å. Ce is bonded in a 12-coordinate geometry to ten Mg and two equivalent Cu atoms. Bothmore » Ce–Cu bond lengths are 3.13 Å.
