Materials Data on Gd(NiP)2 by Materials Project
GdNi2P2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Gd3+ is bonded in a distorted body-centered cubic geometry to eight equivalent P3- atoms. All Gd–P bond lengths are 2.99 Å. Ni+1.50+ is bonded to four equivalent P3- atoms to form a mixture of corner and edge-sharing NiP4 tetrahedra. All Ni–P bond lengths are 2.28 Å. P3- is bonded in a 9-coordinate geometry to four equivalent Gd3+, four equivalent Ni+1.50+, and one P3- atom. The P–P bond length is 2.33 Å.
