A series of new coordination complexes bearing H2pydco, an O-donor ligand, were synthesized and compared to corresponding complexes with H2pydc. The molecular and supramolecular structures were investigated using crystallography, solution phase and high level DFT studies.

A new kind of dendritic-salicylaldehydeimine ligand was synthesized with 1.0G polyamidoamine and salicylaldehyde through schiff reaction, and further formed two kinds of dendritic metal complexes by complexing Cu and Zn. The dendritic-salicylaldehydeimine ligand and its metal complexes were characterized by elemental analysis, IR, NMR and UV. The results indicate that two kinds of dendritic metal complexes with stable structure have been synthesized by complexing Cu and Zn, the yield were 88.2% and 65.2% respectively; Intra-molecular hydrogen bond between the hydroxyl H atom of ph-OH and the N atom of >C=N- has been formed in the ligand; The structures of complexes agree well with the theory.
