Synthesis and electrochemistry of (5Z,5´Z ) 2,2´ (alkane α α α α α,ω ω ω ω ω diyldisulfanyldiyl) bis(5 (2 pyridylmethylene) 3,5 dihydro 4H imidazol 4 one) complexes with cobalt(II) chloride*A series of S alkylated 2 thiohydantoin derivatives containing two 5 (2 pyridylmethylene) 2 sulfanyl 3,5 dihydro 4Н imidazol 4 one moieties linked through a polymethylene bridge with different numbers of carbon atoms was synthesized for the first time. These compounds were obtained by the alkylation of 3 phenyl 5 (2 pyridylmethylene) 2 thiohydantoin or 3 methyl 5 (2 pyridylmethylene) 2 thiohydantoin with different α,ω dibromoalkanes in ac etone or DMF in the presence of potassium carbonate. Complexes of these compounds (L) with CoCl 2 were synthesized. In all cases, the complexes L(CоCl 2 ) 2 were formed regardless of the ratio of L and inorganic salt introduced into the reaction. According to electronic spectro scopic data, the cobalt atom in the complexes has a tetrahedral coordination environment. The synthesized ligands and complexes were electrochemically studied by cyclic voltammetry.Key words: (5Z,5´Z ) 2,2´ (alkane α,ω diyldisulfanyldiyl)bis(5 (2 pyridylmethylene) 3,5 dihydro 4Н imidazol 4 ones, complexes with cobalt(II) chloride, electronic absorption spec troscopy, cyclic voltammetry. * Dedicated to Academician N.

The polydentate ligand, 3-[(2-hydroxy-benzylidene)-amino]-2-thioxo-imidazolidin-4-one, was synthesized by intermolecular cyclocondensation reaction of 2-hydroxybenzaldehyde thiosemicarbazone and ethylchloroacetate. Novel palladium(II) complex was obtained by nucleophilic substitution of both DMSO ligands from cis-[Pd(DMSO)2Cl2] with iminic nitrogen and thiolactamic sulfur from ligand. The structure of compounds was characterized on the basis of their spectral data. The cytotoxic activity of the ligand and palladium(II) complex was studied on tumor cell lines: human colon carcinoma HCT-116 and SW-480 cells using MTT viability test. The results show that investigated palladium(II) complex has significantly greater cytotoxic effect compared to ligand. [Projekat Ministarstva nauke Republike SRbije, br. 172011 and III41010

“…43 The complexes of Pt(II) and Pd(II) are involved thiohydantoin as bidentate ligand. The structure of Tl(I) complex of 5-benzylidene-2-thiohydantoin, 44 and 5-(4'-dimethylaminobenzylidene)-2-thiohydantoin 45 are determined by X-ray methods. Recently, the molecular structure of cyclopentanespiro-5-(2-thiohydantoin) and cyclohexanespiro-5-(2-thiohydantoin) have been established by X-ray analysis by Ahmedova et al 27 For cyclopentanespiro-5-(2-thiohydantoin) two crystallographicaly independent molecules are present in the asymmetric unit in contrast to its dithio-analogue.…”

Synthesis and characterization of new Pt(II) complexes of cyclohexanespiro-5-(2-thiohydantoin) (L1) and cycloheptanespiro-5-(2-thiohydantoin) (L2) are discussed. The new complexes are studied by elemental analysis, IR and 1 H NMR spectroscopy. The free ligands are investigated by UV-Vis, IR, 1 H NMR, 13 C NMR and Raman spectroscopy. The ground-state equilibrium geometries of the ligands L1 and L2 and their complexes with Pt(II) are optimized at the BLYP/CEP-31G theoretical level.
