Abstract
U ovom radu ispitivana je mogućnost nastajanja soli benzensulfonske kiseline i p-toluensulfonske kiseline s odabranim halogenpiridinima: 3-klorpiridinom, 3-brompiridinom, 3-jodpiridinom, 4-jodpiridinom, 2,6-diklorpiridinom, 2,6-dibrompiridinom, 3,5-diklorpiridinom, 3,5-dibrompiridinom, 5-brom-2-klorpiridinom i 5-brom-2-jodpiridinom. Priprava soli provedena je mehanokemijskom sintezom te sintezom iz otopine i suspenzije reaktanata. Dobiveni produkti okarakterizirani su difrakcijom rentgenskog zračenja na praškastom uzorku i razlikovnom pretražnom kalorimetrijom. Za devet soli čiji su jedinični kristali uspješno priređeni, metodom difrakcije rentgenskog zračenja u jediničnom kristalu određene su molekulske i kristalne strukture. Strukturnom analizom priređenih spojeva utvrđeno je da je u svim solima dominantna međumolekulska interakcija između kationa i aniona vodikova veza N–H∙∙∙O. U solima u kojima su kationi jod ili brom supstituirani piridini, ioni su još međusobno povezani halogenskom vezom X∙∙∙O (X = Br, I) koja se ostvaruje između halogenog atoma kationa i kisika sulfonske skupine aniona.
Abstract (english)
The possibility of forming benzenesulfonate and p-toluenesulfonate salts with the following halogenpyridines was studied: 3-chloropyridine, 3-bromopyridine, 3-iodopyridine, 4-iodopyridine, 2,6-dichloropyridine, 2,6-dibromopyridine, 3,5-dichloropyridine, 3,5-dibromopyridine, 5-bromo-2-chloropyridine and 5-bromo-2-iodopyridine. Salts were prepared mechanochemically, by crystallization from solution, and slurry experiments. The obtained products were characterized by powder X-ray diffraction and differential scanning calorimetry. Single crystals were obtained for nine salts, and their molecular and crystal structures were determined by single crystal X-ray diffraction. Structural analysis has shown that the dominant non-covalent interaction in all salts is the N–H∙∙∙O hydrogen bond. In seven salts that contain iodo– or bromo– substituted pyridines as cations, the ions are also interconnected by X∙∙∙O (X = Br, I) halogen bonds formed between the cation halogen atom and the sulfonate anion oxygen atom.
