| Description | Reactions between bromoselenate(IV)-containing solutions, dibromine and salts of pyridinium-family organic cations resulted in structurally diverse, bromine-rich polybromine-bromoselenates(IV): $(4-MePyH)_{5}[Se_{2}Br_{9}][SeBr_{6}](Br_{3})_{2}$ (1), $(2-MePyH)_{2}{[SeBr_{6}](Br_{2}$)} (2), $(PyH)_{2}{[SeBr_{5}]Br(Br_{2})_{2}$} (3), $(1-MePy)_{2}{[SeBr_{6}](Br_{2}$)} (4). The compounds feature halogen and (in the case of 3) 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 1–4; additionally, characterization by Raman spectroscopy was performed. |
