Materials Data on PaBr5 by Materials Project
PaBr5 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two PaBr5 clusters. Pa5+ is bonded to six Br1- atoms to form edge-sharing PaBr6 octahedra. There are a spread of Pa–Br bond distances ranging from 2.65–2.91 Å. There are five inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Pa5+ atom. In the second Br1- site, Br1- is bonded in a water-like geometry to two equivalent Pa5+ atoms. In the third Br1- site, Br1- is bonded in a single-bond geometry to one Pa5+ atom. In the fourth Br1- site, Br1- is bonded in a single-bond geometry to one Pa5+ atom. In the fifth Br1- site, Br1- is bonded in a single-bond geometry to one Pa5+ atom.
