Synthesis and characterization of novel gold(III) complexes with polydentate N-donor ligands based on the pyridine and triazole heterocycles

The coordination chemistry towards Au(III) of pyridine-triazole ligands has been explored. These ligands form neutral and ionic mono-nuclear chloro-complexes. The coordination mode and the formation of the complexes appear strongly influenced by small changes of basicity caused by the introduction of alkyl- of aryl-substituents on the triazole moiety.
