Novel Diphenoxo-Bridged Dinuclear Zinc Complexes: Generation of Phenoxyl-Radical Species and Nuclease Activity
Tridentate ligand PhimpH having N2O donors binds to zinc(II) after deprotonation, affording novel diphenoxo-bridged dinuclear zinc complexes [Zn-2(Phimp)(2)(ClO4)(2)] (1) and [Zn-2(Phimp)(2)(Cl)(2)]center dot CH2Cl2 (2 center dot CH2Cl2). The molecular structure of 2 center dot CH2Cl2 revealed some unique structural features. The phenoxyl-radical complexes were generated at room temperature, and these radical complexes exhibited nuclease activity with pBR322 DNA.
