  Scheme 1

• Associated context:

  Heterocyclic thiolates are ambidentate ligands that are capable of involving either the exocyclic sulfur or the endocyclic nitrogen atoms of the thioamide group in monodentade, chelating or bridging coordination. The introduction of an acid function next to the thiol group, as in 2-mercaptonicotinic acid, leads to other coordination possibilities, such as chelating (O,S) and (N,S), presented in Scheme 1.
