The introduction of a metal into a mesogenic molecule can result in a complex with interesting electrical and magnetic properties. By reacting the non-mesogenic cyclic amine shown in the figure with Ni(NO3)2 · 6H2O in absolute THF the first member of a new class of columnar liquid-crystalline metal complexes with three nitrogen atoms as donor groups has been prepared.
