Materials Data on Nd(NiSn)2 by Materials Project

Abstract

Nd(NiSn)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Nd is bonded in a 12-coordinate geometry to eight Ni and eight Sn atoms. There are four shorter (3.31 Å) and four longer (3.43 Å) Nd–Ni bond lengths. There are four shorter (3.37 Å) and four longer (3.44 Å) Nd–Sn bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to four equivalent Nd and five Sn atoms. There are one shorter (2.51 Å) and four longer (2.58 Å) Ni–Sn bond lengths. In the second Ni site, Ni is bonded in a 8-coordinate geometry to four equivalent Nd and four equivalent Sn atoms. All Ni–Sn bond lengths are 2.57 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent Nd and five Ni atoms. In the second Sn site, Sn is bonded in a 12-coordinate geometry to four equivalent Nd and four equivalent Ni atoms.
