Materials Data on Er3(P3Pd10)2 by Materials Project
Er3(Pd10P3)2 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded to twelve equivalent Pd and six equivalent P atoms to form distorted face-sharing ErP6Pd12 cuboctahedra. All Er–Pd bond lengths are 2.99 Å. All Er–P bond lengths are 3.23 Å. In the second Er site, Er is bonded to sixteen Pd atoms to form distorted ErPd16 tetrahedra that share edges with six equivalent ErPd16 tetrahedra and faces with four equivalent ErP6Pd12 cuboctahedra. There are four shorter (2.85 Å) and twelve longer (3.35 Å) Er–Pd bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 6-coordinate geometry to three Er, nine Pd, and two equivalent P atoms. There are a spread of Pd–Pd bond distances ranging from 2.69–3.04 Å. Both Pd–P bond lengths are 2.39 Å. In the second Pd site, Pd is bonded in a 4-coordinate geometry to one Er, six equivalent Pd, and three equivalent P atoms. All Pd–P bond lengths are 2.50 Å. P is bonded in a 9-coordinate geometry to one Er and eight Pd atoms.
