Materials Data on TmAsPd by Materials Project
TmPdAs crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm is bonded in a 11-coordinate geometry to six equivalent Pd and five equivalent As atoms. There are a spread of Tm–Pd bond distances ranging from 3.05–3.36 Å. There are a spread of Tm–As bond distances ranging from 2.88–2.97 Å. Pd is bonded to six equivalent Tm, two equivalent Pd, and four equivalent As atoms to form a mixture of distorted edge, face, and corner-sharing PdTm6As4Pd2 cuboctahedra. Both Pd–Pd bond lengths are 3.04 Å. There are a spread of Pd–As bond distances ranging from 2.61–2.80 Å. As is bonded in a 9-coordinate geometry to five equivalent Tm and four equivalent Pd atoms.
