Cleavage of the Pt–S bond of thiolated terpyridine–platinum(II) complexes by copper(II) and zinc(II) ions in phosphate buffer

Abstract

Using the chelation of a triamine moiety and an S-bridged heterodinuclear unit, cleavage of the Pt–S bond in the thiolate–platinum complexes, [Pt(terpy)(BAT)]⁴⁺ and [Pt(terpy)(AET)]⁺ is induced by adding transition metals such as Cu²⁺ or Zn²⁺ in phosphate buffer (pH 7–8) at room temp.
