Materials Data on NdSb2Pd by Materials Project

Abstract

NdPdSb2 is beta Sn-derived structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Nd3+ is bonded in a 6-coordinate geometry to six Sb+2.50- atoms. There are a spread of Nd–Sb bond distances ranging from 3.05–3.15 Å. Pd2+ is bonded to six Sb+2.50- atoms to form a mixture of distorted edge and corner-sharing PdSb6 pentagonal pyramids. There are four shorter (3.06 Å) and two longer (3.10 Å) Pd–Sb bond lengths. There are two inequivalent Sb+2.50- sites. In the first Sb+2.50- site, Sb+2.50- is bonded in a 6-coordinate geometry to two equivalent Nd3+ and four equivalent Pd2+ atoms. In the second Sb+2.50- site, Sb+2.50- is bonded in a 6-coordinate geometry to four equivalent Nd3+ and two equivalent Pd2+ atoms.
