资源简介：
SmNiSb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sm3+ is bonded in a 8-coordinate geometry to eight Sb+2.50- atoms. There are four shorter (3.27 Å) and four longer (3.31 Å) Sm–Sb bond lengths. Ni2+ is bonded to four equivalent Sb+2.50- atoms to form a mixture of edge and corner-sharing NiSb4 tetrahedra. All Ni–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 Sm3+ and four equivalent Sb+2.50- atoms. All Sb–Sb bond lengths are 3.11 Å. In the second Sb+2.50- site, Sb+2.50- is bonded in a 8-coordinate geometry to four equivalent Sm3+ and four equivalent Ni2+ atoms.
