Title: Materials Data on Eu2As3 by Materials Project

Abstract

Eu2As3 is Magnesium tetraboride-like structured and crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are five inequivalent Eu2+ sites. In the first Eu2+ site, Eu2+ is bonded in a 8-coordinate geometry to eight As+1.33- atoms. There are a spread of Eu–As bond distances ranging from 3.15–3.31 Å. In the second Eu2+ site, Eu2+ is bonded in a 8-coordinate geometry to eight As+1.33- atoms. There are a spread of Eu–As bond distances ranging from 3.13–3.44 Å. In the third Eu2+ site, Eu2+ is bonded in a 7-coordinate geometry to nine As+1.33- atoms. There are a spread of Eu–As bond distances ranging from 3.09–3.64 Å. In the fourth Eu2+ site, Eu2+ is bonded in a 10-coordinate geometry to ten As+1.33- atoms. There are a spread of Eu–As bond distances ranging from 3.02–3.52 Å. In the fifth Eu2+ site, Eu2+ is bonded to eight As+1.33- atoms to form a mixture of distorted corner, edge, and face-sharing EuAs8 hexagonal bipyramids. There are a spread of Eu–As bond distances ranging from 3.09–3.45 Å. There are six inequivalent As+1.33- sites. In the first As+1.33- site, As+1.33- is bonded in a 7-coordinate geometry to five Eu2+ and two As+1.33- atoms. There are onemore » shorter (2.53 Å) and one longer (2.72 Å) As–As bond lengths. In the second As+1.33- site, As+1.33- is bonded in a 7-coordinate geometry to five Eu2+ and two As+1.33- atoms. The As–As bond length is 2.58 Å. In the third As+1.33- site, As+1.33- is bonded in a 7-coordinate geometry to six Eu2+ and two As+1.33- atoms. The As–As bond length is 2.58 Å. In the fourth As+1.33- site, As+1.33- is bonded in a 7-coordinate geometry to six Eu2+ and one As+1.33- atom. The As–As bond length is 2.58 Å. In the fifth As+1.33- site, As+1.33- is bonded in a 7-coordinate geometry to six Eu2+ and one As+1.33- atom. In the sixth As+1.33- site, As+1.33- is bonded in a 8-coordinate geometry to six Eu2+ and two As+1.33- atoms. The As–As bond length is 2.61 Å.« less
