Materials Data on Pr(NiAs)2 by Materials Project
PrNi2As2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pr3+ is bonded in a distorted body-centered cubic geometry to eight equivalent As3- atoms. All Pr–As bond lengths are 3.21 Å. Ni+1.50+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing NiAs4 tetrahedra. All Ni–As bond lengths are 2.37 Å. As3- is bonded in a 9-coordinate geometry to four equivalent Pr3+, four equivalent Ni+1.50+, and one As3- atom. The As–As bond length is 2.69 Å.
