摘要:

The current literature on the binding of dioxygen and carbon monoxide to iron(II) porphyrinato systems is reviewed. Conditions of measurement and their errors are considered in arriving at a selection of systems that are believed to be comparable. The data from these systems are tabulated and are used to enumerate some of the factors that influence ligand binding.

摘要:

The dissociation reactions of colloidal complexes of Fe(III), Al(III), and Cu(II) formed by binding of the metals to naturally occurring organic ligands and by their inclusion in hydrous oxide colloids are studied by treatment with an excess of a ligand suitable for sensitive spectrophotometric detection under solution conditions favorable to formation of the complex with the color former. A range of rates varying with metal to ligand ratio are found which emphasize the importance of the extension to kinetics of the mixture polyelectrolyte approach which has gained acceptance in discussion of the equilibrium properties of similar complexes. Results do show interpretable relationships to the kinetic behavior of the better studied mononuclear chelate species and some aspects point to a role for mass transport. The ground is prepared for inorganic kineticists to enter this problem area which probably encompasses the subject of bioavailability of metal ion nutrients and toxicants.

摘要:

Similarities and contrasts in the descriptive chemistry of aqua and ammine complexes of mthenium are discussed. The reactivities of the two classes of coordination compounds are compared; both show a remarkable tendency to form complexes with π-accepting ligands, including alkenes and alkynes. The exploitation of Ru(H2O)62+as a versatile preparative reagent is demonstrated.

摘要:

This comment will review reactions involving transition metal ions and tripodal ligands whose donor centers are tertiary phosphine or arsine groups, and will describe typical products that are formed in these reactions. The reactions involving tripodal ligands often have no counterpart in reactions involving ligands with similar donor centers but having shapes other than tripodal. Also, complexes with tripodal ligands often have unique structural properties. Both of these characteristics derive from the particular geometric requirements of tripodal ligands, so we will begin by considering the ways in which these ligands bind to transition metal ions. An exhaustive review covering the whole known range of tripodal ligands will appear elsewhere1.
