Heterobimetallic Zinc and Lanthanide Salicylaldimine Complexes Formed in Self-Assembly Process

The new 3d-4f heterobimetallic salicylaldimine complexes of the formulas ZnLaL2(NO3)5×5H2O, ZnGdL2Cl5×6H2O and ZnGdL3(NO3)5×5H2O, where L is N,N'- bis(salicylidene)-1,3-phenylenediamine, were synthesized by the template-in duced Schiff base condensation reaction between salicylaldehyde and 1,3- phenylene diamine in the presence of appropriate metal ions acting as templates. The complexes were characterized by spectroscopic methods (IR, 1H NMR, ESI-MS) and elemental analysis.
