Materials Data on PrAgAs2 by Materials Project
PrAgAs2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Pr3+ is bonded in a 8-coordinate geometry to eight As2- atoms. There are a spread of Pr–As bond distances ranging from 3.06–3.27 Å. Ag1+ is bonded in a 8-coordinate geometry to four equivalent Ag1+ and four equivalent As2- atoms. All Ag–Ag bond lengths are 2.90 Å. There are two shorter (2.78 Å) and two longer (2.80 Å) Ag–As bond lengths. There are two inequivalent As2- sites. In the first As2- site, As2- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Ag1+ atoms. In the second As2- site, As2- is bonded in a 6-coordinate geometry to four equivalent Pr3+ and two equivalent As2- atoms. Both As–As bond lengths are 2.62 Å.
