Materials Data on ErAsSe by Materials Project

ErAsSe is Matlockite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Er3+ is bonded in a 9-coordinate geometry to four equivalent As1- and five equivalent Se2- atoms. There are a spread of Er–As bond distances ranging from 3.06–3.15 Å. There are a spread of Er–Se bond distances ranging from 2.88–3.02 Å. As1- is bonded in a 8-coordinate geometry to four equivalent Er3+ and four equivalent As1- atoms. There are a spread of As–As bond distances ranging from 2.57–2.94 Å. Se2- is bonded in a 5-coordinate geometry to five equivalent Er3+ atoms.

Materials Data on ErAsSe by Materials Project

ErAsSe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Er3+ is bonded in a 9-coordinate geometry to four equivalent As1- and five equivalent Se2- atoms. There are a spread of Er–As bond distances ranging from 3.06–3.15 Å. There are a spread of Er–Se bond distances ranging from 2.88–3.02 Å. As1- is bonded in a 8-coordinate geometry to four equivalent Er3+ and four equivalent As1- atoms. There are two shorter (2.58 Å) and two longer (2.95 Å) As–As bond lengths. Se2- is bonded in a 5-coordinate geometry to five equivalent Er3+ atoms.
