Materials Data on SmSb2Pd by Materials Project

Abstract

SmPdSb2 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 (3.30 Å) and four longer (3.33 Å) Sm–Sb bond lengths. Pd2+ is bonded to four equivalent Sb+2.50- atoms to form a mixture of corner and edge-sharing PdSb4 tetrahedra. All Pd–Sb bond lengths are 2.72 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 3.19 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 Pd2+ atoms.
