Results for “As-Se-Tb”

Materials Data on TbAsSe by Materials Project

TbAsSe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tb3+ is bonded in a 9-coordinate geometry to four equivalent As1- and five equivalent Se2- atoms. There are a spread of Tb–As bond distances ranging from 3.08–3.18 Å. There are four shorter (2.91 Å) and one longer (3.05 Å) Tb–Se bond lengths. As1- is bonded in a 8-coordinate geometry to four equivalent Tb3+ and four equivalent As1- atoms. There are two shorter (2.59 Å) and two longer (3.00 Å) As–As bond lengths. Se2- is bonded in a 5-coordinate geometry to five equivalent Tb3+ atoms.
