Other ligands containing sulfur as donor atom 

Tn the absence of Eu oxidative depro-tonation of the pale-yellow H2S complex occurs to give the orange ruthenium(TTT) complex [Ru(NH3)5(SH)]. Other examples of complexes containing the SH ligand are [Cr(OH2)5(SH)f+, [W(f, -CsHs)(CO)3(SH)], 

The S-donor ligands SO, S2O2 and SO2 are mentioned in Section 15.2.5 and S-N ligands in Section 15.2.7. Thiocyanate (SCN ) is ambidentate. but towards heavier metaLs it 

Organic thio ligands are well established, examples being the thiols RSH (R = Et, Pr , Bu, the thioethers SMe2, SEt2, tetrahy- 

Dilhiocarbamates and their analogues have 2 potential S-donor atoms joined to a single C atom and their complexes are sometimes called 1,1-dithiolato complexes. If the 2 S atoms are Joined to adjacent C atoms then the equally numerous class of 1,2-dithiolato complexes results. Examples of chelating dithiolenc ligands (drawn for convenience with localized valence bonds and ionic charges) are
