Materials Data on Er10NiSb5 by Materials Project

Abstract

Er10NiSb5 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. there are eight inequivalent Er sites. In the first Er site, Er is bonded in a 5-coordinate geometry to one Ni and four Sb atoms. The Er–Ni bond length is 2.88 Å. There are a spread of Er–Sb bond distances ranging from 3.02–3.48 Å. In the second Er site, Er is bonded in a 5-coordinate geometry to one Ni and four Sb atoms. The Er–Ni bond length is 2.77 Å. There are a spread of Er–Sb bond distances ranging from 3.16–3.45 Å. In the third Er site, Er is bonded in a 6-coordinate geometry to six Sb atoms. There are a spread of Er–Sb bond distances ranging from 3.02–3.46 Å. In the fourth Er site, Er is bonded in a 5-coordinate geometry to one Ni and four Sb atoms. The Er–Ni bond length is 2.72 Å. There are two shorter (3.21 Å) and two longer (3.23 Å) Er–Sb bond lengths. In the fifth Er site, Er is bonded to five Sb atoms to form distorted ErSb5 square pyramids that share a cornercorner with one ErSb5 trigonal bipyramid, edges with two equivalent ErNiSb4 square pyramids, and edges with two equivalent ErSb5 trigonal bipyramids. There are a spread of Er–Sb bond distances ranging from 3.08–3.12 Å. In the sixth Er site, Er is bonded to one Ni and four Sb atoms to form a mixture of distorted corner and edge-sharing ErNiSb4 square pyramids. The Er–Ni bond length is 2.87 Å. There are two shorter (3.14 Å) and two longer (3.15 Å) Er–Sb bond lengths. In the seventh Er site, Er is bonded to five Sb atoms to form a mixture of distorted corner and edge-sharing ErSb5 trigonal bipyramids. There are a spread of Er–Sb bond distances ranging from 2.97–3.24 Å. In the eighth Er site, Er is bonded in a 5-coordinate geometry to one Ni and four Sb atoms. The Er–Ni bond length is 2.77 Å. There are two shorter (3.22 Å) and two longer (3.25 Å) Er–Sb bond lengths. Ni is bonded in a 7-coordinate geometry to seven Er atoms. There are three inequivalent Sb sites. In the first Sb site, Sb is bonded in a 9-coordinate geometry to nine Er atoms. In the second Sb site, Sb is bonded in a 9-coordinate geometry to nine Er atoms. In the third Sb site, Sb is bonded in a 8-coordinate geometry to eight Er atoms.
