Synthesis and Properties of Hybrid Halobismuthates of N-Acetonylpyridinium Derivatives

New hybrid N-acetonylpyridinium, N-(ω-iodoacetonyl)pyridinium, and N-acetonyl-2,6-dimethylpyridinium halobismuthates I–VII have been synthesized and structurally characterized. A preparative method of synthesis is proposed for compounds I, III, and VII, and some individual crystals have been managed to separate and characterize for compounds II, IV–VI. A new type of {K[BiBr6]\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\} _{n}^{{2n - }}$$\end{document} 1D-chains with K+ cations has been revealed in the structure of [C8H10NO]2K[BiBr6] (II). N-acetonyl-2,6-dimethylpyridinium bromobismuthates [C10H14NO]3[Bi2Br9] V and VI (space group P21/n) are polymorphs of similar structure. Iodobismuthates [C8H10NO]4[Bi4I16] (III) and [C10H14NO]4[Bi4I16]⋅0.69I2 (VII) are built of [Bi4I16]4– anions, and [Bi4I16] moieties in the structure of VII are linked into a 1D-anionic chain by molecules I2.
