Recently the authors reported on the syntheses and structural characterization of singly-bridged and doubly-bridged double-cubanes that contain two Fe[sub 4]S[sub 4] or two MoFe[sub 3]S[sub 4] subunits respectively. They proposed these molecules as conceptually relevant for the design and synthesis of speculative models for the active site of nitrogenase. In this communication, the authors report on the oxidative degradation of the MoFe[sub 3]S[sub 4] structural units in the [[MoFe[sub 3]S[sub 4]Cl[sub 2](Cl[sub 4]cat)][sub 2]([mu][sub 2]-S)([mu][sub 2]-L)][sup n[minus]] doubly-bridged double-cubane (L = NH[sub 2]OH; n = 4) DBDC-I and the formation of the hetero-dinuclear thiomolybdate complexes [(Cl[sub 4]cat)Mo(O)([mu]-S)[sub 2]FeCl[sub 2]][sup 2[minus]] and [(S)Mo(O)([mu]-S)[sub 2]FeCl[sub 2]][sup 2[minus]]. 17 refs., 2 figs.
