Pyridyldithiafulvene as N-ligand towards molybdenum carbonyl complexes and evidence of protonation through hydrolysis of lead perchlorate

► Pyridyldithiafulvenes behave as monodentate ligands. ► Coordination of pyridyldithiafulvenes to Mo(CO)5 fragment leads to electroactive complexes. ► Lead perchlorate trihydrate reagent induces the protonation of the pyridyl group.
