Materials Data on SrCeMg6 by Materials Project
SrMg6Ce crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Sr is bonded in a 12-coordinate geometry to ten Mg atoms. There are a spread of Sr–Mg bond distances ranging from 3.21–3.44 Å. There are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 10-coordinate geometry to two equivalent Sr, six Mg, and two equivalent Ce atoms. There are a spread of Mg–Mg bond distances ranging from 3.20–3.30 Å. There are one shorter (3.19 Å) and one longer (3.35 Å) Mg–Ce bond lengths. In the second Mg site, Mg is bonded in a 10-coordinate geometry to two equivalent Sr, six Mg, and two equivalent Ce atoms. There are a spread of Mg–Mg bond distances ranging from 3.02–3.51 Å. Both Mg–Ce bond lengths are 3.22 Å. In the third Mg site, Mg is bonded in a distorted q6 geometry to eight Mg and two equivalent Ce atoms. Both Mg–Ce bond lengths are 3.41 Å. In the fourth Mg site, Mg is bonded in a 12-coordinate geometry to two equivalent Sr and eight Mg atoms. Ce is bonded in a 10-coordinate geometry to ten Mg atoms.
