Abstract

The first member of a water-soluble family of bis(thiosemicarbazone) ligands is reported. It forms a 1:1 complex with Zn" that absorbs intensely in the visible region (λ_max= 414 nm; ε= 1.8(4) x 104M^-1 cm^-1; pH 7.3). Its affinity for Zn^II (KD = 5.9(3) x 10^-9 M at pH 7.3) was determined by competition with ligand ethylene glycol O,O-bis(2-aminoethyl)-N,N,N,N-tetraacetic acid. Its potential application as a chromophoric probe was demonstrated by estimation of the Zn^II binding affinities of the soluble metal-binding domains of two plant metal-transporting proteins.
