Materials Data on DyAsSe by Materials Project
DyAsSe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Dy3+ is bonded in a 9-coordinate geometry to four equivalent As1- and five equivalent Se2- atoms. There are a spread of Dy–As bond distances ranging from 3.08–3.17 Å. There are a spread of Dy–Se bond distances ranging from 2.90–3.04 Å. As1- is bonded in a 8-coordinate geometry to four equivalent Dy3+ and four equivalent As1- atoms. There are two shorter (2.59 Å) and two longer (2.99 Å) As–As bond lengths. Se2- is bonded in a 5-coordinate geometry to five equivalent Dy3+ atoms.
