The ability of pyridyldithiafulvenes to react as monodentate ligand with Mo(CO)₆ and Pb(ClO₄)₂ has been investigated. The corresponding molybdenum carbonyl complexes have been isolated while no coordination to lead has been observed. As evidenced by X-ray crystal structure analysis, protonation of the pyridyl moiety has occurred due to the propensity of lead perchlorate trihydrate to hydrolyze in acetonitrile. The spectroscopic and redox properties of the molybdenum complexes as well as the pyridinium dithiafulvenes have been compared with their precursors and discussed.
