The synthesis, characterization, and mesomorphic properties of a new series of Schiff bases 2a–h and metal complexes 1a–h–M are prepared and their mesomorphic properties studied. Two single crystallographic structures of 2d (n= 12, m= 1) and 1g–Pd (n= m= 12) were determined by X-ray analysis. Both compounds crystallize in a triclinic space group P− 1. A dimeric structure formed by intermolecular H-bonds in 2d was observed, giving ...
