Structures and Properties of Polymeric Iodobismuthates Cat{[BiI4]} with Pyridinium-Derived Cations
摘要
Abstract
Two novel bismuth(III) iodide complexes (1,3,4-MePy){[BiI4]} (1) and (3-Br-1-MePy){[BiI4]} (2)) were synthesized by the reaction of iodides of corresponding cations with BiI3 in organic solvents. Crystal structures of the compounds were determined by single crystal X-ray diffraction. For both complexes, the thermal stability was studied, and the optical band gap values were experimentally estimated.
