TRIIODIDE SALTS OF 4-DIMETHYLAMINO- AND 3-BROMO-1-METHYLPYRIDINIUM: CRYSTAL STRUCTURES AND FEATURES OF NON-COVALENT I⋯I INTERACTIONS IN SOLIDS

Triiodide salts of pyridinium-derived cations of the composition CatI 3 (Cat = 4-dimethylaminopyridinium ( 1 ), 3-bromo-1-methylpyridinium ( 2 )) are prepared by reactions of respective cation iodide and I 2 in the HI solution and characterized by single crystal XRD and Raman spectroscopy. The optic...

Beschreibung
Zusammenfassung:	Triiodide salts of pyridinium-derived cations of the composition CatI 3 (Cat = 4-dimethylaminopyridinium ( 1 ), 3-bromo-1-methylpyridinium ( 2 )) are prepared by reactions of respective cation iodide and I 2 in the HI solution and characterized by single crystal XRD and Raman spectroscopy. The optical band gaps are calculated from the diffuse reflectance spectroscopy data.
