Materials Data on PrAs by Materials Project

PrAs is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pr3+ is bonded to six equivalent As3- atoms to form a mixture of corner and edge-sharing PrAs6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Pr–As bond lengths are 3.05 Å. As3- is bonded to six equivalent Pr3+ atoms to form a mixture of corner and edge-sharing AsPr6 octahedra. The corner-sharing octahedral tilt angles are 0°.
