    RATIONALE Heavy metals are both a problem for the environment and an important resource for industry. Their selective extraction by means of organic ligands therefore is an attractive topic. The coordination of three thiacrown ethers to late 3d-metal ions was investigated by a combination of electrospray ionization mass spectrometry (ESI-MS) and electron paramagnetic resonance (EPR). METHODS The mass spectrometric experiments were carried out in an ion trap mass spectrometer with an ESI source. Absolutebinding constants were estimated by comparison with data for 18-crown-6/Na+. EPR spectroscopy was used as a complementary method for investigating the CuI/CuII redox couple. RESULTS The study found that thiacrown ethers preferentially bind traces of copper even at an excess of other metal ions (CoII, NiII, and ZnII). The absolute association constants of the CuI complexes were about 108?M1, and about two orders of magnitude lower for the other 3d-metal cations. The EPR spectra demonstra
