Trends in redox potentials of transition metal complexes

Synthesis, Crystal Structures, Magnetic Properties and Photoconductivity of C60 and C70 Complexes with Metal Dialkyldithiocarbamates M(R2dtc)x, where M = CuII, CuI, AgI, ZnII, CdII, HgII, MnII, NiII, and PtII; R = Me, Et, and nPr

“…Related octahedral M III -(dtc) 3 1-/0 (M 3+ /M 2+ transition) are reduced at -0.77 V for V 3+/2+ , and -0.92 V for Co 3+/2+ , whereas the reduction potential for Mn 3+/2+ (-0.08 V) is shifted to positive values (all vs. Ag/AgCl). [30] C 60 has the first E 0/-potential at -0.485 V(vs. Ag/AgCl). [32] …”

“…It is possible to vary molecular structures of M(R 2 dtc) x by changing "M" or the length of alkyl substituents (R). Donor properties of M(R 2 dtc) x can also be varied from weak donors to strong ones [30] potentially able to ionize fullerenes. Some of M(R 2 dtc) x have broad absorption in the visible range or outstanding magnetic properties [for example, Fe III -(Et 2 dtc) 2 Cl is the first single-component ferromagnet with T c = 2.46 K] [31] and, therefore, they can be used as light harvesting or magnetic components for the complexes.…”

Sulfation Patterns of Saccharides and Heavy Metal Ion Binding

“…First, the quantity of ions detected depends on the sulfation pattern, with ac lear preference of mercury to the monosulfated functionalized GCE. [65] CV provedt ob eav aluable additional toolw ith whicht o furtherd ecipher sugar metal interaction variances. We assume that the two peaks for msHA4-GCE originate either from the formation of two distinctive mercury-HA complexes or from the presence of two oxidation states.…”

Comments on “Decontamination of solutions containing Cu(II) and ligands tartrate, glycine and quardol using metallic iron” [J. Hazard. Mater. (175 (2010) 452–459)]

“…(3) shows clearly that Cu removal primarily depends on the relative stability of Cu II -L and Fe II -L complexes. It is well-known that the redox reactivity of metals ions is influenced by complexation [4,12]. A rough rule of thumb could be: Cu II removal by Fe 0 is only possible if Fe II -L is more stable than Cu II -L. In the case of simple hydratation (L = H 2 O), Cu removal is possible as documented by standard electrodes potential given in Ref.…”
