Materials Data on SbPd2 by Materials Project

SbPd2 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are four inequivalent Pd sites. In the first Pd site, Pd is bonded in a 4-coordinate geometry to four equivalent Sb atoms. All Pd–Sb bond lengths are 2.78 Å. In the second Pd site, Pd is bonded in a 5-coordinate geometry to five Sb atoms. There are a spread of Pd–Sb bond distances ranging from 2.71–2.87 Å. In the third Pd site, Pd is bonded in a 4-coordinate geometry to four Sb atoms. There are a spread of Pd–Sb bond distances ranging from 2.67–2.72 Å. In the fourth Pd site, Pd is bonded in a 4-coordinate geometry to four Sb atoms. There are a spread of Pd–Sb bond distances ranging from 2.66–2.81 Å. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a 9-coordinate geometry to nine Pd atoms. In the second Sb site, Sb is bonded in a 8-coordinate geometry to eight Pd atoms.

Materials Data on Dy3(SbPd2)4 by Materials Project

Dy3(Pd2Sb)4 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Dy is bonded in a 1-coordinate geometry to eight Pd and five Sb atoms. There are four shorter (3.05 Å) and four longer (3.23 Å) Dy–Pd bond lengths. There are one shorter (2.98 Å) and four longer (3.34 Å) Dy–Sb bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 6-coordinate geometry to three equivalent Dy and three equivalent Sb atoms. All Pd–Sb bond lengths are 2.71 Å. In the second Pd site, Pd is bonded in a 7-coordinate geometry to three equivalent Dy and four Sb atoms. There are one shorter (2.73 Å) and three longer (2.93 Å) Pd–Sb bond lengths. There are three inequivalent Sb sites. In the first Sb site, Sb is bonded in a body-centered cubic geometry to eight equivalent Pd atoms. In the second Sb site, Sb is bonded to four equivalent Dy and eight Pd atoms to form SbDy4Pd8 cuboctahedra that share corners with four equivalent SbDy4Pd8 cuboctahedra, edges with two equivalent SbDy6 octahedra, and faces with eight equivalent SbDy4Pd8 cuboctahedra. In the third Sb site, Sb is bonded to six equivalent Dy atoms to form edge-sharing SbDy6 octahedra.
