An All-rounder Aminoguanidine based Ligand, Its Unusual Anionic Zinc(II) and Cadmium(II) Coordination Complexes and Their Biological Implications

Multipurpose coordination flexibility of a bioactive ligand 1, 3-bis (5-bromo-2-hydroxyphenyl-methylideneamino) guanidine hydrochloride (H5Brsal-dag.HCl) is reported. The chelation of the ligand with Zn(II) ion after deprotonation forms an unusual anionic complex...
