Solid solutions of 4-methylpyridinium bromoiodobismuthates have been isolated from aqueous solutions and structurally characterized. It was found that the composition of the resulting solid solutions [PiH]4Bi2X10, [PiH]BiX4, and [PiH]3Bi2X9 (PiH = 4-methylpyridinium; X = Br, I) depends on the ratio of organic cation/bismuth and bromine/iodine in the initial solution. The existence of two polymorphic modifications of [PiH]BiX4 in the system formed at different ratios of halide ions has been demonstrated. Possible reasons for the unequal occupation of halogen positions in the crystal lattice by different halogen atoms are analyzed.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
