title: Monothioacids as novel chelating groups. The Au(III) complexes of N-methylthioamide monothiooxamic acid.
abstract: CH3HNCSCSOH(LH) forms AuLCl2, AuLBr2, AuL2Cl and AuL2Br complexes in acid media. The complexes are characterised by their elemental analysis and the vibrational spectra. A thorough analysis of the vibrational spectra is carried out to reveal the structure of these complexes. From this study we could conclude that all complexes exhibit a square-planar geometry around the metal ion and that in all cases the ligand acts as a bidentate, coordinating through the sulphur atoms of the thioamide and monothioacid functional groups, forming chelate ring systems.
