Funada, Atsushi published the artcileConformational Transformations of (C12H25NH3+)(Pyridinesulfonate) in the Solid State, Related Products of pyridine-derivatives, the publication is Chemistry – An Asian Journal (2016), 11(6), 915-925, database is CAplus and MEDLINE.
The phase-transition behaviors, crystal structures, and dielec. properties of four kinds of simple 1:1 organic salts of (C12H25NH3+)(benzenesulfonate) and (C12H25NH3+)(pyridine sulfonates) were examined from the viewpoint of intermol. hydrogen-bonding interactions and dynamic conformational transformation in mol. assemblies. Crystals of (C12H25NH3+)(benzenesulfonate) and (C12H25NH3+)(3-pyridinesulfonate) were isostructural and solid-solid and solid-liquid-crystal smectic A (SmA) phase transitions were observed These two crystals formed rodlike cation-anion assemblies. However, the two salts, (C12H25NH3+)(2-pyridinesulfonate) and (C12H25NH3+)(4-pyridinesulfonate), formed largely bent L-shaped cation-anion conformations. Interesting conformational transformations from rodlike to L-shaped assemblies were observed in (C12H25NH3+)(2-pyridinesulfonate) and (C12H25NH3+)(3-pyridinesulfonate).
