Materials Data on Sr(NiSb)2 by Materials Project
SrNi2Sb2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a distorted body-centered cubic geometry to eight equivalent Sb3- atoms. All Sr–Sb bond lengths are 3.51 Å. Ni2+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing NiSb4 tetrahedra. All Ni–Sb bond lengths are 2.53 Å. Sb3- is bonded in a 9-coordinate geometry to four equivalent Sr2+, four equivalent Ni2+, and one Sb3- atom. The Sb–Sb bond length is 3.06 Å.
