Materials Data on UNiSb2 by Materials Project
UNiSb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. U4+ is bonded in a 8-coordinate geometry to eight Sb3- atoms. There are four shorter (3.14 Å) and four longer (3.27 Å) U–Sb bond lengths. 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 2.61 Å. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 8-coordinate geometry to four equivalent U4+ and four equivalent Sb3- atoms. All Sb–Sb bond lengths are 3.07 Å. In the second Sb3- site, Sb3- is bonded in a 8-coordinate geometry to four equivalent U4+ and four equivalent Ni2+ atoms.
