Synthesis, characterization, DNA binding and cleavage activity of homoleptic zinc(II) β-oxodithioester chelate complexes

Effect of Substituents on the Crystal Structures, Optical Properties, and Catalytic Activity of Homoleptic Zn(II) and Cd(II) β-oxodithioester Complexes

“…In the majority of complexes reported so far, the coordination sphere of the metal is closely controlled through the use of bridging/chelating/monodentate ligands containing N/O/S donor atoms. − Dithioesters have found applications in ionic resins for the separation of transition-metal ions, for Ag + -selective membrane electrodes, and as hair-growing agents in combination with zinc . The β-oxodithioesters are strongly O ∧ S-chelating ligands and have been utilized to synthesize homo- and heteroleptic complexes with several transition metals, yielding a stable delocalized six-membered ring about the metal center. , The metal complexes of organosulfur ligands including those of β-oxodithioesters have served as catalysts in a variety of organic transformation reactions and also exhibited biological properties such as antileishmanial and anticancer activities . Intriguing coordination polymeric structures and photoluminescence properties of Tl­(I) β-oxodithioester complexes displaying varied polymeric structures have also been described .…”
