Abstract

Pr11Hg45 crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are five inequivalent Pr sites. In the first Pr site, Pr is bonded in a 8-coordinate geometry to fourteen Hg atoms. There are a spread of Pr–Hg bond distances ranging from 3.22–3.45 Å. In the second Pr site, Pr is bonded in a 12-coordinate geometry to fourteen Hg atoms. There are a spread of Pr–Hg bond distances ranging from 3.22–3.91 Å. In the third Pr site, Pr is bonded in a 4-coordinate geometry to sixteen Hg atoms. There are four shorter (3.40 Å) and twelve longer (3.50 Å) Pr–Hg bond lengths. In the fourth Pr site, Pr is bonded in a 3-coordinate geometry to sixteen Hg atoms. There are a spread of Pr–Hg bond distances ranging from 3.45–3.66 Å. In the fifth Pr site, Pr is bonded in a 10-coordinate geometry to sixteen Hg atoms. There are a spread of Pr–Hg bond distances ranging from 3.25–3.75 Å. There are fourteen inequivalent Hg sites. In the first Hg site, Hg is bonded in a 9-coordinate geometry to five Pr and eight Hg atoms. There are a spread of Hg–Hg bond distances ranging from 3.07–3.25 Å. In the second Hg site, Hg is bonded in a tetrahedral geometry to four equivalent Pr atoms. In the third Hg site, Hg is bonded in a 9-coordinate geometry to three Pr and six Hg atoms. There are a spread of Hg–Hg bond distances ranging from 2.91–3.07 Å. In the fourth Hg site, Hg is bonded in a distorted body-centered cubic geometry to four Pr and four Hg atoms. There are two shorter (2.95 Å) and two longer (3.10 Å) Hg–Hg bond lengths. In the fifth Hg site, Hg is bonded in a 8-coordinate geometry to four Pr and four Hg atoms. There are a spread of Hg–Hg bond distances ranging from 2.85–3.05 Å. In the sixth Hg site, Hg is bonded in a 3-coordinate geometry to three Pr and five Hg atoms.
