Phase Behavior and Proton Conductivity in Crown Ether-Based Supramolecular Sodium Hydrogen Sulfate Complexes.

ABSTRACT: This study deals with the preparation and solid-state characterization, as well as structural and phase transition features of supramolecular complexes composed of sodium hydrogen sulfate (NaHSO₄) and two crown ether ligands, namely, 15-crown-5 and benzo-15-crown-5. Single crystals for each compound were grown, and their structures were elucidated via single-crystal X-ray diffraction (XRD) analysis, which highlighted the following compositions: [15-crown-5·Na]-HSO₄ (1) and [benzo-15-crown-5·Na]-HSO₄ (2). Microcalorimetric analyses, hot-stage microscopy, and variable-temperature powder X-ray diffraction were employed to analyze thermal stability and phase transition behaviors.
