Schiff base complexes are formed through the condensation of aldehydes or ketones with primary amines. The Schiff base compounds usually contain O, N and any other donor atoms, which easily form versatile complexes with metal ions. In recent years, much interest has been focused on the Schiff base compounds and their complexes. The Schiff base complexes have been widely used in the magnetic materials, catalysis, biological activity and many other fields.Study on the interactions between metal ions and the Schiff base ligands is important for the investigation of their properties and applications. In order to further investigate the synthesis and self-assembly of the Schiff base complexes, 17 Schiff base ligands derived from salicylaldehyde had been designed and synthesized. 24 Schiff base complexes had been synthesized and their crystal structures have been determined by X-ray diffraction. The influence of the reaction conditions, proportion of starting materials, solvents, anions, bridging groups, etc. on the structures of the complexes have been investigated.As a result, the reaction conditions, the proportion of starting materials, solvents, anions, and bridging groups, have important influence for the structures of such complexes.
