Abstract

The synthesis and characterization of three new [Mn.sup.II] complexes was carried out by using [N.sub.3]O-donor amino-carboxylate ligands. The complexes were found to be good structural models for the oxalate metabolizing enzymes.

3. Tuning the redox properties of manganese(II) and its implications to the electrochemistry of manganese and iron superoxide dismutases

Author

Sjodin, Martin, Gatjens, Jessica, Tabares, Leandro C., Thuery, Pierre, Pecoraro, Vincent L., and Sun Un

Subjects
Electrostatic interactions -- Research, Manganese -- Chemical properties, Organometallic compounds -- Chemical properties, Redox potential -- Analysis, Chemistry
Abstract

The dependence of the redox potential of manganese(II) on the electron-donating properties of substituents in the ligand periphery is quantified by the Hammett parameter [[sigma].sub.para] of the substituent. The studies have shown that the more distant electrostatic contributions are the source of metal specific enzymatic activity.

4. The relationship between the manganese(II) zero-field interaction and Mn(II)/Mn(III) redox potential of Mn[(4'-X-terpy).sub.2] complexes

Author

Subjects
Redox potential -- Research, Spectrum analysis -- Research, Chemistry
Abstract

The zero-field parameters and redox potentials are examined for a series of closely related complexes, Mn(II)[(4'-X-terpy).sub.2], where X's are substituents that have varied electron-donating/withdrawing capacities. The studies have shown that Mn(II) zero-field interactions might provide a new way for studying manganese binding proteins.

5. Tri- and pentanuclear tungsten-(mu-S)-M clusters (M = W, Cu, Ag)

Subjects

Abstract

The characterization of the compounds containing the syn-{OW(mu-S)}2 and {OMo(S)-(mu-S)2} cores, stabilized by thiocyanate is reported. This reaction is applied to synthesize the trinuclear [{S2W (super VI)(mu-S)2}2 W(super IV) =O](super2-), and to explore its ability to act as a bis(bidentate) ligand in the coordination to Cu(super +1) and Ag(super +1).
