Materials Data on Tm3(P3Pd10)2 by Materials Project

Tm3(Pd10P3)2 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded to sixteen Pd atoms to form distorted TmPd16 tetrahedra that share edges with six equivalent TmPd16 tetrahedra and faces with four equivalent TmPd12 cuboctahedra. There are four shorter (2.83 Å) and twelve longer (3.34 Å) Tm–Pd bond lengths. In the second Tm site, Tm is bonded to twelve equivalent Pd atoms to form distorted face-sharing TmPd12 cuboctahedra. All Tm–Pd bond lengths are 2.98 Å. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 4-coordinate geometry to one Tm, six equivalent Pd, and three equivalent P atoms. All Pd–Pd bond lengths are 3.03 Å. All Pd–P bond lengths are 2.49 Å. In the second Pd site, Pd is bonded in a 6-coordinate geometry to three Tm, nine Pd, and two equivalent P atoms. There are one shorter (2.70 Å) and four longer (2.98 Å) Pd–Pd bond lengths. Both Pd–P bond lengths are 2.39 Å. P is bonded in a 9-coordinate geometry to eight Pd atoms.

Materials Data on TmPPd by Materials Project

TmPdP crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm is bonded in a 5-coordinate geometry to six equivalent Pd and five equivalent P atoms. There are a spread of Tm–Pd bond distances ranging from 3.01–3.25 Å. There are a spread of Tm–P bond distances ranging from 2.81–2.89 Å. Pd is bonded to six equivalent Tm, two equivalent Pd, and four equivalent P atoms to form a mixture of distorted face, edge, and corner-sharing PdTm6P4Pd2 cuboctahedra. Both Pd–Pd bond lengths are 2.99 Å. There are a spread of Pd–P bond distances ranging from 2.53–2.76 Å. P is bonded in a 9-coordinate geometry to five equivalent Tm and four equivalent Pd atoms.
