Materials Data on Dy9(SbO)5 by Materials Project

Abstract

Dy9(SbO)5 crystallizes in the tetragonal P4/n space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a distorted single-bond geometry to five Sb and one O atom. There are one shorter (3.14 Å) and four longer (3.16 Å) Dy–Sb bond lengths. The Dy–O bond length is 2.34 Å. In the second Dy site, Dy is bonded in a distorted single-bond geometry to five Sb and one O atom. There are a spread of Dy–Sb bond distances ranging from 3.09–3.18 Å. The Dy–O bond length is 2.28 Å. In the third Dy site, Dy is bonded in a 4-coordinate geometry to two equivalent Sb and four O atoms. There are one shorter (3.31 Å) and one longer (3.38 Å) Dy–Sb bond lengths. There are a spread of Dy–O bond distances ranging from 2.19–2.45 Å. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a 5-coordinate geometry to seven Dy atoms. In the second Sb site, Sb is bonded to five Dy atoms to form SbDy5 square pyramids that share corners with four equivalent ODy4 tetrahedra and a cornercorner with one ODy5 trigonal bipyramid. There are two inequivalent O sites. In the first O site, O is bonded to five Dy atoms to form distorted ODy5 trigonal bipyramids that share a cornercorner with one SbDy5 square pyramid, corners with four equivalent ODy4 tetrahedra, and edges with four equivalent ODy4 tetrahedra. In the second O site, O is bonded to four Dy atoms to form ODy4 tetrahedra that share a cornercorner with one SbDy5 square pyramid, corners with four equivalent ODy4 tetrahedra, a cornercorner with one ODy5 trigonal bipyramid, an edgeedge with one ODy4 tetrahedra, and an edgeedge with one ODy5 trigonal bipyramid.
