Mono-oxo-bis-dithioveratrol-molybdate - In Solution a Model for Arsenite Oxidase and in the Solid State a Coordination Polymer with Unprecedented Binding Motifs

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

Methyl- and methoxy-substituted di[1,4]benzodithiio[2,3-b:2,3-e]-pyridines as new electron donor compounds: Synthesis, molecular structure, electrochemical properties, and EPR studies

Two new derivatives of di[1,4]benzodithiino[2,3-b:2,3-e]pyridine (5) tetrasubstituted with methyl (7) and methoxy (8) groups at the 2,3,9 and 10 positions have been prepared from 2,3,5,6-tetrachloropyridine, by cyclization reaction with the bidentate nucleophiles, 4,5-dimethyl-and 4,5-dimethoxy-benzene-1,2-dithiol. Cyclic voltammograms for the oxidation of both polyheterocyclic compounds 7 and 8 in CH2Cl2 exhibit two consecutive redox couples. The first pairs are due to the equilibria between the initial compounds and their radical cations, while in the second couples, the electrogenerated radical cations are in equilibrium with the corresponding dications. Radical cations of these molecules have been generated in fluid solution, by oxidation of the parent compounds with thallium(III) trifluoroacetate in trifluoroacetic acid in the case of 7, and by irradiation of a CH2Cl2 solution containing trifluoroacetic acid (10%) in the case of 8. Both species were analyzed by electron paramagnetic resonance (EPR). X-Ray analysis of the molecular structures of both 7 and 8 shows a stable chair-shaped conformation with interplanar angles between the phenyl rings and the pyridine ring of 139.9 and 141.4° for 7 and 133.7° for 8.

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.
