Abstract

Polynuclear bismuth(III) iodide complexes with 1-ethyl-4-dimethylaminopyridinium (1-EtDMAP)4[Bi8I28] (1) and (1-EtDMAP)BiI4 (2) have been obtained by the reactions of bismuth(III) iodide with an organic iodide salt cations in organic solvents and characterized by X-ray diffraction. The optical properties and thermal stability of the obtained compounds have been studied.

Highlights

Interest in the chemistry of halide complexes of p-elements is largely due to the variety of their structural types [1]
On the other hand, halogenated metals [21,22,23] can possess a number of physicochemical properties that are of interest from the point of view of materials science
Screening using a wide range of organic cations as salt precursors remains the most rational way to search for halogenated metalates that are promising from the point of view of materials science

Summary

Introduction

Interest in the chemistry of halide complexes of p-elements is largely due to the variety of their structural types [1]. We obtained and structurally characterized two new bismuth iodide complexes with 1-ethyl4-dimethylaminopyridinium cation (-EtDMAP), namely (1-EtDMAP)4[Bi8I28] (1) and (1-EtDMAP)BiI4 (2). After partial evaporation of the solvent at room temperature, dark red crystals were obtained.
