Sulphur-containing ligands

Multinuclear ds-d10 metal ion complexes with sulphur-containing ligands. J. P. Fackler, Prog. Inorg. Chem., 1976, 21, 55-90 (73). 

The X-ray photoelectron spectra of metal complexes of sulphur-containing ligands sulphur 2/ -binding energies. R. A. Walton, Coord. Chem. Rev., 1980, 31, 183-220 (88). 

Spectra and electronic structure of complexes with sulphur-containing ligands. C. K. Jorgensen, Inorg. Chim. Acta, Rev., 1968, 2, 65-88 (295). 

Unlike the specifically bound metals which participate in reversible redox reactions extraneously bound transition metals are well able to induce uncontrolled oxidation of sulphur containing ligands The so called metal driven Haber Weiss reaction is responsible for the formation of oxidised sulphur species leading to sulphonic acid. For example ... 

The use of pH-sensitive fluorescent indicators as spray reagents has been recently examined for the determination of sulphur-containing pesticides and amino acids separated by TLC [158,159]. The procedure is adapted from a ligand-exchange method of Frei and Mallet [160]. The separated pesticides are brominated directly on the TLC plate. This treatment oxidizes the pesticides and liberates hydrobromic acid as a side product. On... 

Mechanisms for metal immobilization include intracellular uptake with complexation to ligands such as sulphur-containing peptides (metallothio-neins) and carboxylic acids (citrate, malate, oxalate) (Gadd, 1993 Sarret et al., 1998, 2002 Fomina et al., 2005c). Some fungi can also precipitate... 

The tridentate sulphur containing ligand in Ph2SbS2P(OPr )2 also favours the formation of polymer chains. However, the structure differs from the complex mentioned above and contains one strong Sb—S bond of 254 pm and two weaker intermolecular... 

This attenuation of the electronegativity variation in the earlier columns of the Periodic Table is even more pronounced when S is compared with Se. A choice of selenium-containing ligands (20, 22, 23) have Xopt 0.05 to 0.1 unit below that of the corresponding sulphur-containing ligands. Before the work described in this review, the spectra of complexes of Se 2 were not known.
