Highly anisotropic imine ligands have been synthesised and complexed to Re(
I). Two series of ligands and complexes were obtained with various chain le
ngths, showing smectic and nematic phases for the ligands and only a nemati
c phase for the complexes. The identity of the crystal smectic phase in the
ligands was studied by X-ray diffraction and identified as a crystal J pha
se.
