摘要:

Recent extensive research into the aqueous solution chemistry of molybdenum has led to the preparation and characterization of aquo ions in oxidation states (II) through (VI). It is appropriate at this time to report on the area and comment on the diversity of chemistry exhibited by these ions.

摘要:

A simple perturbation model for calculating electron delocalization in valence-trapped (class II) mixed-valence compounds is described and its application illustrated. Optical absorption spectroscopy and polarized neutron diffraction are two experimental techniques for estimating valence delocalization. Both are described, with examples.

摘要:

Recent electrochemical investigations of binary mesityl compounds of the early transition metals and of a series of nickel(0) complexes illustrate the influence of the nature and oxidation state of the central atom and of the ligands on the redox behavior. On the basis of macrocyclic nickel(II) complexes, the effects of ring size and unsaturation of the ligand on the redox potential and on the site of electron addition [one-electron reduction of nickel(II) or of the ligand] are demonstrated. The electrochemical data may be used for an explanation or even for a prediction of the course of chemical reactions. A remarkable process is the nucleophilic substitution of unsaturated organic substrates (maleic acid anhydride, quinones) within the coordination sphere of nickel(0) which yields a radical anion.
