Materials Data on TmNiPb by Materials Project
TmNiPb crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm is bonded in a 11-coordinate geometry to five equivalent Ni and six equivalent Pb atoms. There are a spread of Tm–Ni bond distances ranging from 2.97–3.17 Å. There are a spread of Tm–Pb bond distances ranging from 3.19–3.32 Å. Ni is bonded in a 9-coordinate geometry to five equivalent Tm and four equivalent Pb atoms. There are three shorter (2.66 Å) and one longer (2.90 Å) Ni–Pb bond lengths. Pb is bonded in a 10-coordinate geometry to six equivalent Tm and four equivalent Ni atoms.
