Materials Data on Bi7RhBr8 by Materials Project

RhBi7Br8 is beta Np structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four RhBi7Br8 clusters. Rh is bonded in a pentagonal bipyramidal geometry to seven Bi atoms. There are a spread of Rh–Bi bond distances ranging from 2.73–2.76 Å. There are seven inequivalent Bi sites. In the first Bi site, Bi is bonded in a distorted T-shaped geometry to one Rh and two Br atoms. There are one shorter (2.93 Å) and one longer (3.05 Å) Bi–Br bond lengths. In the second Bi site, Bi is bonded to one Rh and four Br atoms to form corner-sharing BiRhBr4 square pyramids. There are a spread of Bi–Br bond distances ranging from 2.87–3.11 Å. In the third Bi site, Bi is bonded to one Rh and four Br atoms to form corner-sharing BiRhBr4 square pyramids. There are a spread of Bi–Br bond distances ranging from 2.88–3.10 Å.
