Abstract
Three new linear gold(I) complexes of the formulas [(Ipr)Au(S 2CN(CH3)2)] (1), [(Ipr)Au (S 2CN(C2H5)2)] (2) and [(Ipr)Au(S 2CN(C7H7)2)] (3) [where Ipr = 1,3-bis(2,6-di-isopropylphenyl)imidazol-2-ylidenegold] have been prepared by the reaction of equimolar amounts of 1,3-bis(2,6-di-isopropylphenyl)imidazol-2- ylidenegold(I)chloride, [(Ipr)Au(Cl)] with sodium dimethyldithiocarbamate monohydrate, sodium diethyl dithiocarbamatetrihydrate and dibenzyl dithiocarbamate, respectively. The structures of the complexes have been determined by single X-ray crystallography. All gold(I) complexes (1-3) are iso-structural i.e. linear geometry. The complex (1) crystallizes in monoclinic space group 'P21/a', while the complexes (2) and (3) crystallize in orthorhombic space group 'Pna21'. The IR spectra and 1H as well as 13C NMR measurements of the Au(I) complexes (1-3) corroborate well with their single crystal X-ray structure analysis. These gold(I) complexes show moderate potential anti-cancer activities against A549 (human lung carcinoma), HCT15 (human colon cancer), and HeLa (human cervical cancer) cell lines.
