Abstract

N,N-Dimethylpiperidinium iodide (PIP₁₁I) has P2₁/n symmetry at -150 °C. The crystal packing of the ions of PIP₁₁I is compared with that reported for N,N-dimethylpyrrolidinium iodide (PYR ₁₁I) and N,N-dimethylmorpholinium iodide (MORP₁₁I). Despite the differences in cation structure, PYR₁₁I and PIP ₁₁I have essentially identical ion crystal packing. This is not the case, however, for PIP₁₁I and MORP₁₁I. The phase behavior and thermal stability of the three salts have also been compared to examine the influence of crystal packing on thermal properties.
