Materials Data on PrAs3 by Materials Project
PrAs3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pr3+ is bonded to twelve equivalent As1- atoms to form a mixture of corner and face-sharing PrAs12 cuboctahedra. All Pr–As bond lengths are 3.16 Å. As1- is bonded in a square co-planar geometry to four equivalent Pr3+ atoms.
