The highly coloured copper(II) chelates of 3-hydroxyphenylrhodanine and (4,5-dibromo-3-hydroxyphenyl)rhodanine have been prepared and characterised by elemental analysis, i.r. spectroscopy, and magnetic susceptibility measurements.The 3-hydroxyphenylrhodanine chelate has been shown to be useful in the sensitive spectrophotometric determination of copper(II).E.s.r. measurements show that the chelate forms a tetrapyridine solvate in pyridine solution.Mixed-ligand chelates consisting of copper(II) and 3-hydroxyphenylrhodanine and an amino-acid such as threonine, or a polyaminocarboxylicacid such as ethylenediaminetetra-acetic acid, have also been prepared and characterised.Dissolution of these copper(II) chelates of rhodanine in chloroform leads to the formation of the dithiocarbamate chelates bis(N-chloroacetyl-N-3-hydroxyphenyldithiocarbamato)copper(II) and bis(N-chloroacetyl-N-4,5-dibromo-3-hydroxyphenyldithiocarbamato)copper(II).
