Coordination metal complexes between copper and various halogens disubstituted (Cl, Br, I) N-(4-(4'-n-alkoxybenzoyloxy)salicylidene) 4-n-butylaniline have been synthesized.These copper derivatives show mesomorphic properties and exhibit, in particular, a nematic phase over a wide temperature range.The physical characteristics of all these compounds are compared and discussed.A special emphasis is given to the effect of the size and the position of the halogen substituents.

Copper, nickel and palladium complexes with N-(4-(4'-n-alkoxybenzoyloxy) salicylidene)-4-n-butylaniline and N-(4-(4'-n-hexadecyloxybenzoyloxy) salicylidene)-4-n-alkoxyaniline have been synthesized.The copper and palladium derivatives show mesomorphic properties and exhibit a nematic phase over a large temperature range.In contrast, the nickel derivatives do not show any mesomorphic behavior.The liquid-crystalline-phase transitions were determined using a differential scanning calorimeter and a polarizing microscope.All these physical characteristics are compared and discussed.
