Materials Data on Ho5CuPb3 by Materials Project
Ho5CuPb3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 7-coordinate geometry to two equivalent Cu and five equivalent Pb atoms. Both Ho–Cu bond lengths are 2.84 Å. There are a spread of Ho–Pb bond distances ranging from 3.16–3.61 Å. In the second Ho site, Ho is bonded in a 6-coordinate geometry to six equivalent Pb atoms. All Ho–Pb bond lengths are 3.27 Å. Cu is bonded to six equivalent Ho atoms to form face-sharing CuHo6 octahedra. Pb is bonded in a 9-coordinate geometry to nine Ho atoms.
