Efficient and unique cooperation of three zinc(ii) ions in the hydrolysis of diribonucleotides by a trinuclear zinc(ii) complex

Abstract

A trinuclear Zn ²⁺ complex is prepared using a ligand having six pyridine moieties, N,N,N′,N′,N″,N″ -hexakis(2-pyridylmethyl)[tris(2-aminoethyl)amine] (L ³ ), and efficiently hydrolyses diribonucleotides at pH 7 and 50 °C, showing much greater activity than a dinuclear Zn ₂ L ² complex.
