Mono-oxo-bis-dithioveratrol-molybdate was synthesized, structurally characterized, and investigated with respect to its oxo-transfer activity. The latter was compared with the activity of the analogous tungsten complex. The title complex is a structural model for molybdopterin bearing arsenite oxidase and both complexes catalyze oxo-transfer reactions successfully to 100 % conversion. With the dithioveratrol ligand the oxidation of triphenylphosphine proved to be faster for the tungsten complex, which is untypical. The solid-state structure of the molybdenum complex exhibits an unexpected and very unusual polymeric structural motif consisting of the complex anion mono-oxo-bis-dithioveratrol-molybdate, sodium cations, and methanol. Infinite double-decker strands are formed with sodium bridges between the ether functions of two ligands in one strand and the Mo=O moiety of the second strand. Copyright
Transition-metal Complexes of Crown Ether Benzodithiolenes

Three new dithiolene ligands have been synthesized, two of which have the novel feature of a crown ether ring attached directly to the benzene ring of an aryl dithiolene.Complexes with transition metals have been prepared and their (1)H, (13)C NMR, UV/VIS and electrochemical properties recorded.The information obtained appears to reflect variations in the degree of delocalisation in the metallodithiolene ring within the series of complex types.
