Abstract

Bis-(2-hydroxy-4-(n-alkoxy) benzaldimino) copper (II) and bis-(2-hydroxy-4 (n-alkoxy) benzaldimino) nickel (II) complexes have been synthesized by the reaction of 2-hydroxy-4-(n-alkoxy) benzaldehyde with tetraamine complexes of Cu(II) and Ni(II) under template condition. Cu(II) and Ni(II) complexes of 1,2-bis-(2-hydroxy-4-(n-alkoxy) benzaldimino) ethane and 1,3-bis-(2-hydroxy-4-(n-alkoxy) benzaldimino) propane have been synthesized from the imine complexes by amine exchange with 1,2-diaminoethane and 1,3-diaminopropane, respectively. The complexes have been characterized by spectral and magnetic studies. Some of these complexes exhibit mesogenic properties. This has been correlated to the structures of the complexes.
