1H NMR and X-ray studies on hydrogen bonding in alkyloxy ethanols and their MgCl2 adducts

► Concentration dependence of 1H chemical shift of OH in alkyloxy ethanols. ► Temperature dependence of hydrogen bonding in alkyloxy ethanols. ► Influence of alcohol alkyl chain length on the solubility of MgCl2. ► Influence of alcohol chain length on crystallization of MgCl2/alkyloxy ethanol adduct. ► Alkyloxy ethanols showed a chelated structure in MgCl2 adducts.
