Materials Data on Tm5NiPb3 by Materials Project
Tm5NiPb3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 7-coordinate geometry to two equivalent Ni and five equivalent Pb atoms. Both Tm–Ni bond lengths are 2.72 Å. There are a spread of Tm–Pb bond distances ranging from 3.15–3.64 Å. In the second Tm site, Tm is bonded in a 6-coordinate geometry to six equivalent Pb atoms. All Tm–Pb bond lengths are 3.23 Å. Ni is bonded to six equivalent Tm atoms to form face-sharing NiTm6 octahedra. Pb is bonded in a 9-coordinate geometry to nine Tm atoms.
