Materials Data on Pr2Ni12As7 by Materials Project

Kristin Persson
Pr2Ni12As7 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are two inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded to six equivalent As3- atoms to form distorted PrAs6 pentagonal pyramids that share corners with six equivalent NiAs5 square pyramids, corners with twelve NiAs4 tetrahedra, edges with twelve NiAs4 tetrahedra, and faces with two equivalent PrAs6 pentagonal pyramids. All Pr–As bond lengths are 3.05 Å. In the second Pr3+...
