Mixed halide hybrid halobismuthates and their in situ transformations

During a formation of four mixed hybrid halobismuthates (two of them have new structures) from solutions containing both Br⁻ and I⁻ ions, solid products enriched with iodine were isolated. Either oxidation or drying of mother liquors resulted in products with even higher iodine contents, up to pure iodobismuthates. All the compounds were characterized by a set of comprehensive methods (NMR, X-ray, DRS, etc.).
