Materials Data on NdCoSb2 by Materials Project
NdCoSb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Nd3+ is bonded in a 8-coordinate geometry to eight Sb+2.50- atoms. There are four shorter (3.29 Å) and four longer (3.35 Å) Nd–Sb bond lengths. Co2+ is bonded to four equivalent Sb+2.50- atoms to form a mixture of edge and corner-sharing CoSb4 tetrahedra. All Co–Sb bond lengths are 2.56 Å. There are two inequivalent Sb+2.50- sites. In the first Sb+2.50- site, Sb+2.50- is bonded in a 8-coordinate geometry to four equivalent Nd3+ and four equivalent Sb+2.50- atoms. All Sb–Sb bond lengths are 3.10 Å. In the second Sb+2.50- site, Sb+2.50- is bonded in a 8-coordinate geometry to four equivalent Nd3+ and four equivalent Co2+ atoms.
