Materials Data on Th2Br5 by Materials Project
Th2Br5 crystallizes in the cubic Im-3m space group. The structure is three-dimensional and consists of two Th2Br5 frameworks. Th is bonded to five Br atoms to form corner-sharing ThBr5 square pyramids. There are four shorter (2.93 Å) and one longer (3.05 Å) Th–Br bond lengths. There are two inequivalent Br sites. In the first Br site, Br is bonded in a linear geometry to two equivalent Th atoms. In the second Br site, Br is bonded in an L-shaped geometry to two equivalent Th atoms.
