Crown-containing azomethines and their zinc complexes were prepared. Examination of their structure by H-1 and Li-7 NMR and electronic spectroscopy showed that, in accordance with the concept of hard and soft acids and bases, the hard lithium cation coordinates to the crown ether fragment with the formation of mono- (Li) and binuclear (Li, Zn) complexes.
