Materials Data on Ce2Mn7Al10 by Materials Project
Abstract
Al10Ce2Mn7 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 10-coordinate geometry to ten Mn and nine Al atoms. There are a spread of Ce–Mn bond distances ranging from 3.18–3.43 Å. There are a spread of Ce–Al bond distances ranging from 3.02–3.19 Å. In the second Ce site, Ce is bonded in a 1-coordinate geometry to five Mn and eleven Al atoms. There are a spread of Ce–Mn bond distances ranging from 3.17–3.49 Å. There are a spread of Ce–Al bond distances ranging from 3.10–3.41 Å. There are five inequivalent Mn sites. In the first Mn site, Mn is bonded in a 12-coordinate geometry to one Ce, three Mn, and seven Al atoms. There are a spread of Mn–Mn bond distances ranging from 2.49–2.61 Å. There are a spread of Mn–Al bond distances ranging from 2.52–2.69 Å. In the second Mn site, Mn is bonded in a 12-coordinate geometry to one Ce, two equivalent Mn, and eight Al atoms. Both Mn–Mn bond lengths are 2.50 Å. There are a spread of Mn–Al bond distances ranging from 2.54–2.74 Å. In the third Mnmore »
