摘要
The new ligand bis-(1,4-sodium thiolactate) butane (L)-O2CCH3S-(CH2)4SCHCH3CO2- has been prepared from the reaction of disodium salt of thiolactic acid and 1,4-dichlorobutane, while the disodium thiolactate was prepared instanteously through the reaction of thiolactic acid with NaOH. Mono and dinuclear complexes were obtained by direct reaction of the above ligands with H[AuCI4] in 1 : 1, 2:1, 1:2, 2:2 and 3:1 ligands to metal molar ratio. The prepared complexes were characterized by elemental analysis, spectral studies FTIR (Fourier transform Infrared) and UV-Vis, magnetic measurement, conductivity measurement and IHNMR for the ligand (L) and some of the complexes. The conductance data indicate that the complexes of the formulas Na[Au(SCH3CHCOO)2], Na[Au(SCH3CHCOO)(OOCCHCH3SH)2] and [Au(L)]Cl are 1:1 electrolyte. Electronic spectra and magnetic moment values indicate the presence of square planner geometry around Au(III) ions.
