Materials Data on Re3(SBr)7 by Materials Project

Re3(SBr)7 is alpha La structured and crystallizes in the trigonal P31c space group. The structure is zero-dimensional and consists of four Re3(SBr)7 clusters. Re7+ is bonded to five S2- and two Br1- atoms to form distorted face-sharing ReS5Br2 pentagonal bipyramids. There are a spread of Re–S bond distances ranging from 2.36–2.47 Å. There are one shorter (2.55 Å) and one longer (2.57 Å) Re–Br bond lengths. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 3-coordinate geometry to three equivalent Re7+ atoms. In the second S2- site, S2- is bonded in a 6-coordinate geometry to two equivalent Re7+ and one S2- atom. The S–S bond length is 2.08 Å. In the third S2- site, S2- is bonded in a 6-coordinate geometry to two equivalent Re7+, one S2-, and one Br1- atom. The S–Br bond length is 2.81 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Re7+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Re7+ atom. In the third Br1- site, Br1- is bonded in a 3-coordinate geometry to three equivalent S2- atoms.
