Materials Data on Dy5CuPb3 by Materials Project

Abstract

Dy5CuPb3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded to two equivalent Cu and five equivalent Pb atoms to form a mixture of distorted face, edge, and corner-sharing DyCu2Pb5 pentagonal bipyramids. Both Dy–Cu bond lengths are 2.90 Å. There are a spread of Dy–Pb bond distances ranging from 3.14–3.52 Å. In the second Dy site, Dy is bonded in a 6-coordinate geometry to six equivalent Pb atoms. All Dy–Pb bond lengths are 3.31 Å. Cu is bonded to six equivalent Dy atoms to form face-sharing CuDy6 octahedra. Pb is bonded in a 9-coordinate geometry to nine Dy atoms.
