5-(Pyridylmethylidene)-substituted 2-thiohydantoins and their complexes with CuII, NiII, and CoII: Synthesis, electrochemical study, and adsorption on the cystamine- …
Abstract A series of Cu II, Ni II, and Co II complexes with 5-(pyridylmethylidene)-substituted 2- thiohydantoins (L) were synthesized by the reactions of the corresponding organic ligands with MCl 2· n H 2 O. The resulting complexes have the composition LMCl 2 (M= Cu or Ni) or L 2 MCl 2 (M= Co). The reactions with N (3)-unsubstituted thiohydantoins afford complexes containing four-membered metallacycles, in which the metal ion is coordinated by the S ...
