Three novel polybromide complexes of bismuth(iii) - (2,6-MePyH)[BiBr(Br)] (1), (Hbpp){[BiBr](Br)} (2) and (3-ClPyH){[BiBr](Br)} (3) - were synthesized. The results of an extended screening involving a set of organic cations resulting in the formation/non-formation of Bi(iii) polybromides are presented and discussed. The nature of BrBr interactions in Bi(iii) polybromides was investigated by theoretical methods, enabling the estimation of their energies.

A new family of bismuth coordination compounds - Bi(iii) polybromides - is introduced. Four representatives of this class - (N-EtPy)3[Bi2Br9](Br2)2 (1), (4-MePyH)3[Bi2Br9](Br2) (2), (H2bpe){[BiBr5]}(Br2) (3) and (BPB)2[BiBr5(Br3)](Br3)(Br2) (4) - were obtained in a simple way from HBr solutions of BiBr3 with added Br2, highlighting the diversity of the structural types in the new family of complexes.
