Abstract

Pd13Pb9 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are seven inequivalent Pd sites. In the first Pd site, Pd is bonded in a 12-coordinate geometry to six Pd and six Pb atoms. There are a spread of Pd–Pd bond distances ranging from 2.95–3.12 Å. There are a spread of Pd–Pb bond distances ranging from 2.88–2.99 Å. In the second Pd site, Pd is bonded in a 4-coordinate geometry to six Pd and five Pb atoms. There are a spread of Pd–Pd bond distances ranging from 2.95–3.12 Å. There are a spread of Pd–Pb bond distances ranging from 2.88–3.28 Å. In the third Pd site, Pd is bonded in a 11-coordinate geometry to five Pd and six Pb atoms. There are one shorter (2.98 Å) and one longer (3.01 Å) Pd–Pd bond lengths. There are a spread of Pd–Pb bond distances ranging from 2.77–3.02 Å. In the fourth Pd site, Pd is bonded in a 6-coordinate geometry to five Pd and six Pb atoms. There are one shorter (3.06 Å) and one longer (3.07 Å) Pd–Pd bond lengths. There are a spread of Pd–Pb bond distances ranging from 2.76–3.00 Å. In the fifth Pd site, Pd is bonded in a 6-coordinate geometry to five Pd and six Pb atoms. There are one shorter (3.09 Å) and one longer (3.11 Å) Pd–Pd bond lengths. There are a spread of Pd–Pb bond distances ranging from 2.77–2.99 Å. In the sixth Pd site, Pd is bonded to six Pd and six Pb atoms to form a mixture of distorted corner and face-sharing PdPd6Pb6 cuboctahedra. There are a spread of Pd–Pb bond distances ranging from 2.88–3.13 Å. In the seventh Pd site, Pd is bonded to six Pd and six Pb atoms to form a mixture of distorted corner and face-sharing PdPd6Pb6 cuboctahedra. There are a spread of Pd–Pb bond distances ranging from 2.88–3.11 Å. There are five inequivalent Pb sites. In the first Pb site, Pb is bonded in a 9-coordinate geometry to nine Pd atoms. In the second Pb site, Pb is bonded in a 9-coordinate geometry to eight Pd atoms. In the third Pb site, Pb is bonded in a 10-coordinate geometry to ten Pd atoms. In the fourth Pb site, Pb is bonded in a 7-coordinate geometry to seven Pd atoms. In the fifth Pb site, Pb is bonded in a distorted body-centered cubic geometry to eight Pd atoms.
