Pyrazole-based allylpalladium complexes: Supramolecular architecture and liquid crystal behaviour

Mesomorphic properties of allylpalladium complexes based on 3-alkyloxyphenylpyrazole ligands are determined. Lamellar mesophases SmA are established at temperatures between ca. 40 and 80 °C. The X-ray structure of one of the studied compounds is described, showing interdigitated layer-like supramolecular arrangement.
