Abstract

Pd13Sn9 crystallizes in the trigonal P3_121 space group. The structure is three-dimensional. there are eight inequivalent Pd sites. In the first Pd site, Pd is bonded in a 12-coordinate geometry to six Pd and six Sn atoms. There are a spread of Pd–Pd bond distances ranging from 2.86–3.05 Å. There are a spread of Pd–Sn bond distances ranging from 2.79–2.90 Å. In the second Pd site, Pd is bonded in a 6-coordinate geometry to five Pd and six Sn atoms. There are a spread of Pd–Pd bond distances ranging from 2.88–3.06 Å. There are a spread of Pd–Sn bond distances ranging from 2.71–2.94 Å. In the third Pd site, Pd is bonded in a 12-coordinate geometry to six Pd and six Sn atoms. There are two shorter (2.86 Å) and two longer (3.01 Å) Pd–Pd bond lengths. There are a spread of Pd–Sn bond distances ranging from 2.78–2.93 Å. In the fourth Pd site, Pd is bonded to six Pd and six Sn atoms to form a mixture of distorted face and corner-sharing PdSn6Pd6 cuboctahedra. There are a spread of Pd–Pd bond distances ranging from 2.91–2.99 Å. There are a spread of Pd–Sn bond distances ranging from 2.82–2.99 Å. In the fifth Pd site, Pd is bonded in a 6-coordinate geometry to five Pd and six Sn atoms. There are one shorter (2.89 Å) and one longer (3.06 Å) Pd–Pd bond lengths. There are a spread of Pd–Sn bond distances ranging from 2.69–2.93 Å. In the sixth Pd site, Pd is bonded to six Pd and six Sn atoms to form a mixture of distorted face and corner-sharing PdSn6Pd6 cuboctahedra. Both Pd–Pd bond lengths are 2.98 Å. There are a spread of Pd–Sn bond distances ranging from 2.82–3.00 Å. In the seventh Pd site, Pd is bonded in a 6-coordinate geometry to five Pd and six Sn atoms. There are one shorter (2.89 Å) and one longer (3.03 Å) Pd–Pd bond lengths. There are a spread of Pd–Sn bond distances ranging from 2.69–2.90 Å. In the eighth Pd site, Pd is bonded in a 4-coordinate geometry to six Pd and seven Sn atoms. There are a spread of Pd–Sn bond distances ranging from 2.80–3.33 Å. There are five inequivalent Sn sites. In the first Sn site, Sn is bonded in a 7-coordinate geometry to eight Pd atoms. In the second Sn site, Sn is bonded in a 9-coordinate geometry to nine Pd atoms. In the third Sn site, Sn is bonded in a distorted body-centered cubic geometry to eight Pd atoms. In the fourth Sn site, Sn is bonded in a 9-coordinate geometry to nine Pd atoms. In the fifth Sn site, Sn is bonded in a 10-coordinate geometry to ten Pd atoms.
