[Zn2]2+ as an analogue of the calomel dication [Hg2]2+ was isolated in the form of the solvent stabilized salt [Zn2(THF)6]2+[BAr4F]2−, for which the coordination environment is readily tuneable due to the lability of the solvent molecules.

upon oxidation of the dicopper(I) complex of a tetrahydroxy bis(tridentate) ligand, [Cu2(6H4)(NCMe)2]2+. The dicopper(I) complex of the analogous tetramethoxy N6-ligand, [Cu2(5)(NCMe)2]2+, instead reversibly binds O2. Deprotonation of [Cu(2H)(CO)]+ and [Cu(2H)(NCMe)]+ afforded the neutral derivatives Cu(2)(CO) and Cu2(2)2, respectively. The dicopper(I) derivative Cu2(2)2 can be reoxidized, reprotonated

The activity of nitrogenase enzymes, which catalyze the conversion of atmospheric dinitrogen to bioavailable ammonia, is most commonly assayed by the reduction of acetylene gas to ethylene. Despite the practical importance of acetylene as a substrate, little is known concerning its binding or activation in the iron-rich active site.

the μ-isocarbonyl derivative Cp2V(μ-OC)V(CO)5 as a transient species, which has been characterized in solution by IR analysis. By reaction of VCp2 with V(13CO)6 followed by treatment with 12CO, the ionic dicarbonylderivative [VCp2(12CO)2][V(13CO)6] is formed, thus showing that during the formation of the ionic compound no redistribution of the carbonyl ligands between the two metal centers occurs.
