Reactions between bromoselenate(IV)-containing solutions, dibromine and salts of pyridinium-family organic cations resulted in structurally diverse, bromine-rich polybromine-bromoselenates(IV): (4-MePyH)[SeBr]SeBr (), (2-MePyH){SeBr} (), (PyH){[SeBr]Br(Br)} (), (1-MePy){SeBr} (). The compounds feature halogen and (in the case of ) chalcogen bonding in solid state, resulting in formation of supramolecular architectures of different dimensionality. DFT calculations allowed estimation of the energies of non-covalent interactions in -; additionally, characterization by Raman spectroscopy was performed.
