Abstract: Polynuclear bromoantimonates(III) with alkanediyl-bis(3-methylpyridinium) cations (3-MePyCn2+—(3-MePyC2)3[Sb2Br9]2 (1), (3-MePyC3)2[β-Sb4Br16] (2), and (3-MePyC4)2[α-Sb4Br16] (3)—and bromobismuthate(III) (3-MePyC3)3[Bi2Br9]2 (4) have been synthesized by reacting solutions of Sb2O3 (Bi2O3) in HBr with bromides of the corresponding organic cations. Differences in the structure between compounds 1–3 and bromobismuthates with analogous cations (4 and previously studied compounds) have been considered.
