Nickel complexes molecular magnets

Other interesting compounds are copper and nickel complexes of (p-alkoxyphenyl)-ma-londialdehydes, 27. The synthesis, characterization, thermal behavior. X-ray diffraction studies and magnetic properties of a number of these complexes were performed by Haase et al. [68]. It was found that nickel complexes show liquid crystalline SmA phases over a broad temperature range with low melting points (85 °C), while copper complexes show nonidentified mesomorphic behavior. This behavior is different from that observed for n = 5 copper complex reported by Blake et al. [69] who observed a nematic phase. Models for the molecular...
