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.

Abstract: Hybrid bromobismuthates of N-alkylated derivatives of 2- and 3-methylpyridine, (C15H20N2)2Bi2Br10 (I), (C17H24N2)2Bi2Br10 (II), (C18H26N2)3(Bi2Br9)2 (III), (C14H18N2)(H3O)BiBr6 ? 2H2O (IV), (C14H18N2)2BiBr6IBr2 (V), (C16H22N2)3(Bi2Br9)2 (VI), and (C18H26N2)3(Bi2Br9)2 (VII), are synthesized in concentrated HBr and characterized by physicochemical methods. The structures of complexes I–VII are studied by X-ray structure analysis (CIF files CCDC nos. 1946844–1946850). Complexes I and II contain anions [Bi2Br10]4–. Anions [Bi2Br9]3– are found in the structures of compounds III, VI, and VII. Bis(3-methyl-1-pyridino)ethane bromobismuthate IV contains cations H3O+ and anions [BiBr6]3– and, unlike other bromobismuthates, decomposes at low temperatures. In presence of HI vapors, double bromobismuthate V containing the [BiBr6]3– and IBr2 – anions crystallizes along with compound IV.
