Materials Data on Nb3InSe12 by Materials Project
Nb3InSe12 crystallizes in the tetragonal P4/mnc space group. The structure is three-dimensional. there are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded in a 8-coordinate geometry to eight Se+1.50- atoms. There are four shorter (2.66 Å) and four longer (2.75 Å) Nb–Se bond lengths. In the second Nb5+ site, Nb5+ is bonded in a 8-coordinate geometry to eight Se+1.50- atoms. There are a spread of Nb–Se bond distances ranging from 2.63–2.78 Å. In3+ is bonded in a rectangular see-saw-like geometry to four equivalent Se+1.50- atoms. All In–Se bond lengths are 2.93 Å. There are four inequivalent Se+1.50- sites. In the first Se+1.50- site, Se+1.50- is bonded in a 3-coordinate geometry to two Nb5+ and one In3+ atom. In the second Se+1.50- site, Se+1.50- is bonded in a 2-coordinate geometry to two Nb5+ atoms. In the third Se+1.50- site, Se+1.50- is bonded in a 2-coordinate geometry to two equivalent Nb5+ and one Se+1.50- atom. The Se–Se bond length is 2.37 Å. In the fourth Se+1.50- site, Se+1.50- is bonded in a 2-coordinate geometry to two equivalent Nb5+ and one Se+1.50- atom.
