“…The geometry of dications (bond lengths and angles) is general and comparable with our previously reported structures. [ 42–45 ] The molecular structure of bromobismuthate anion, [Bi 2 Br 9 ] 3− is well‐known. [ 39 ] The Bi‐Br interatomic distances are in two major categories of terminal (Brt) and bridging (Brb) halogen atoms.…”

“…In this article, we tried to investigate the phosphonium‐bromobismuthate structural correlations in the title compound and the other hybrids reported in the Cambridge Structural Database (CSD). In addition, following our previous studies on the applications of quaternary phosphonium derivatives, [ 42–46 ] herein we report a selective, simple, and fast method for the synthesis of benzimidazole and benzoxazole derivatives using title compound as a heterogenous Lewis acid catalyst under solvent‐free conditions. As far as we know, there is no example of using bismuth compounds as catalyst for the synthesis of the abovementioned heterocycles.…”

A new hybrid phosphonium bromobismuthate compound was synthesized and characterized by 1H NMR, 13C NMR, 31P NMR, FT‐IR, differential scanning calorimetry (DSC) and single‐crystal X‐ray diffraction analysis. The crystal packing structures of title compound were stabilized by various intermolecular interactions especially of the type CH···Br hydrogen bonds between phosphonium cations and [Bi2Br9]3− anion. The relative contribution of various close contacts and 2D fingerprint plots of title compound and three analogous structures obtained from Cambridge Structural Database (CSD) were investigated by Hirshfeld surface analysis. Furthermore, the catalytic activity of title compound was investigated in heterocyclization reaction for the synthesis of significant and pharmacologically useful benzimidazole and benzoxazole derivatives. The results indicated that the yields of the product for aldehydes bearing p‐substituents and o‐substituents were higher than for m‐substituent ones. In addition to selectivity, simplicity of operation, waste minimization, ease of manipulation, short reaction time, excellent yield of product, and easy workup, this technique uses title compound as the catalyst, which is green, recyclable, soft, remarkably nontoxic, and easy to handle.

The compound 1,1′‐(ethane,1,2‐diyl)ditriphenylphosphonium hexamolybdate dimethylsulfoxide {C2H4[P(C6H5)3]2}{Mo6O19}·SO (CH3)2 (I) was prepared, and 1H‐NMR, 13C‐NMR, Fourier transform‐infrared, differential scanning calorimetry and single crystal X‐ray diffraction analysis were used to characterize the titled compound. Crystallographic data showed that compound I crystallized in the monoclinic crystal system in C2/c space group. The compound (I) was used for selective synthesis of 2,4,5‐tri aryl imidazole derivatives under solvent‐free conditions efficiently. Because of hindrance of the catalyst, the yields of products for aldehydes bearing para substituents are higher than the aldehydes bearing ortho substituents, and for aromatic aldehydes with meta substituents are very low.
