Abstract
Solid solutions of pyridinium bromo-iodobismutates were isolated from aqueous solutions and structurally characterized. The composition of the resulting solid solutions [HPy]BiX4 and [HPy]3Bi2X9 (X = Br, I) was found to depend on the ratios of pyridinium/bismuth and bromine/iodine in the initial solution. The existence of five polymorphic modifications in the system for [HPy]BiX4 compounds was shown. Two different polymorphs were found for iodobismuthate [HPy]BiI4.
