1D-Bromobismuthates of Dipyridinoalkane Derivatives

Abstract

The following bromobismuthates of organic cations (dipyridinoalkane derivatives) are synthesized and characterized: (4-NH₂PyC₅)BiBr₅ (I), (2-MePyC₂)BiBr₅ (II), (2-NH₂PyC₁₀)BiBr₅ · 0.65H₂O (III), (2-NH₂PyC₁₀)₄H₅O₂(BiBr₆)₃ (IV), (2-NH₂PyС₆)₂KBi₂Br₁₁ (V), (2-NH₂PyC₆)H₃OBiBr₆ · 2.33H₂O (VI), and (2-NH₂PyC₆)₃(BiBr₆)₂ · CH₃CN (VII). Three compounds obtained (I–III) contain the zigzag 1D chain (BiBr₅)_n. A new type of 1D chains, (KBi₂Br₁₁)_n, is found in the structure of compound V. Pseudo-1D chains of BiBr₆³⁻ anions can be observed in the 3D structures of compounds IV, VI, and VII. The crystallographic data were deposited with the Cambridge Crystallographic Data Centre (CIF files CCDC 1569478 (I)–1569484 (VII), respectively).
