Abstract: Aerial oxidation of solution of chemically synthesized Mo-Fe-Scluster [Cl2FeS2MoS2FeCl2]2-has been shown to yield a 1. 50: 1 mixture of MoOS32-and MoS42-.It is evident that the ratio of the concentration of MoOS32-and MoS42-is lower than that produced by the oxidative degradation of natural FeMo-co (△CMoOS32-/△CMoS42- =3:1), so it can be inferred that the oxidative degradation of the cluster containing MoS4core can not give the same result with the oxidative degradation of natural FeMo-co, and there should be three sulfur atoms in molybdenum-micro-surrounding on nitrogenase.

Key words: Nitrogenase, Molybdenum-micro-surronding, Mo-Fe-S cluster, Oxidativedegradation
