Materials Data on PrTeAs by Materials Project

PrAsTe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Pr3+ is bonded in a 9-coordinate geometry to four equivalent As1- and five equivalent Te2- atoms. There are a spread of Pr–As bond distances ranging from 3.11–3.31 Å. There are a spread of Pr–Te bond distances ranging from 3.22–3.33 Å. As1- is bonded in a 6-coordinate geometry to four equivalent Pr3+ and two equivalent As1- atoms. Both As–As bond lengths are 2.65 Å. Te2- is bonded in a 5-coordinate geometry to five equivalent Pr3+ atoms.
