Resumo:
1-Alkyl-3-methylimidazolium tetrachloropalladate(ii) salts ([C-n-mim](2)[PdCl4], n = 10, 12, 14, 16, 18) containing a single, linear alkyl-chain substituent on the cation have been synthesised and their behaviour characterised by differential scanning calorimetry, polarising optical microscopy and small-angle X-ray scattering. The salts display thermotropic polymorphism, exhibiting both crystal-crystal transitions and, for n = 14-18, the formation of a thermotropic smectic liquid crystalline phase.
