Materials Data on Pr(NiP)2 by Materials Project
PrNi2P2 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 P3- atoms. All Pr–P bond lengths are 3.07 Å. Ni+1.50+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing NiP4 tetrahedra. All Ni–P bond lengths are 2.30 Å. P3- is bonded in a 9-coordinate geometry to four equivalent Pr3+, four equivalent Ni+1.50+, and one P3- atom. The P–P bond length is 2.48 Å.
