Three new o-thioetherphenol ligands have been synthesized: 1,2-bis(3,5-di-tert-butyl-2-hydroxyphenylsulfanyl)ethane (H(2)bse), 1,2-bis (3,5-di-tert-butyl-2-hydroxyphenylsulfanyl)benzene (H(2)bsb), and 4,6-di-tert-butyl-2-phenylsulfanylphenol (Hpsp). Their complexes with copper(II) were prepared and investigated by UV-Vis-, EPR-spectroscopy, their electro- and magnetochemistry have also been studied: [Cu-II(psp)(2)] (1). [Cu-2(II)(bse)(2)] (2), [Cu-2(II)(bsb)(2)] (3), [Cu-II(bsb)(py)(2)] (4). The crystal structures of the ligands H(2)bse, H(2)bsb, Hpsp and of the complexes 1, 2, 3, 4 have been determined by X-ray crystallography. (C) 2002 Elsevier Science B.V. All rights reserved.
