Bromo‐ and Polybromoantimonates(V): Structural and Theoretical Studies of Hybrid Halogen‐Rich Halometalate Frameworks

Cation‐dependent reactions “[SbBr6]3−+Br2+HBr+CationBrx” result in the formation of bromide/polybromide complexes with zero‐, one‐, two‐, or three‐dimensional supramolecular frameworks and different Br/Sb ratios (up to 11). Seven new compounds representing six structural types were characterized by XRD and thermogravimetric analysis and DFT calculations enabled estimation of the energies of the Br⋅⋅⋅Br contacts (1.1–4.6 kcal mol−1).
