value is frequently taken as a measure for the extent of twosite interactions on molecules of interest (Eq. 1). Recent progress in the redox chemistry of multimetallic transition-metal complexes and clusters is reviewed. Special attention is paid to high-nuclearity complexes wherein redox-active sites (e.g., ferrocenyl pendants or Ru centers) are assembled in a close proximity with a well-defined geometry via the covalent or coordination bonds. A special emphasis is placed on literature survey for paddlewheel diruthenium(II,III) complexes coordinated by axial or equatorial ferrocenyl ligands, polyferrocenyl compounds in the form of wire, star, and ring, ferrocenyl-based dendrimers, and ligand-mediated molecular triangles and squares. Finally, future prospects of these mixed-valent systems are briefly discussed.

The catalytic, electrocatalytic, or photocatalytic conversion of CO2 into useful chemicals in high yield for industrial applications has so far proven difficult. Herein, we present our work on the electrochemical reduction of CO2 in seawater using a boron‐doped diamond (BDD) electrode under ambient conditions to produce formaldehyde. This method overcomes the usual limitation of the low yield of higher‐order products, and also reduces the generation of H2. In comparison with other electrode materials, BDD electrodes have a wide potential window and high electrochemical stability, and, moreover, exhibit very high Faradaic efficiency (74 %) for the production of formaldehyde, using either methanol, aqueous NaCl, or seawater as the electrolyte. The high Faradaic efficiency is attributed to the sp3‐bonded carbon of the BDD. Our results have wide ranging implications for the efficient and cost‐effective conversion of CO2.

“…[2] It is accepted that these species can combine the catalytic, [3] electrochemical, optical and magnetic properties of organometallic or transition-metal units, with the benefits generally attributed to dendrimers, such as site isolation, [4] precise steric environments, recyclability [5] and potential cooperative effects. Other promising aspects of metallodendrimer chemistry are found in supramolecular chemistry, [6] nanosciences, [7] biology and medicine.…”

Metallodendrimers are an important class of materials with valuable properties and applications in a large number of areas. Herein, we report a highly efficient route for the synthesis of carbosilane dendrimers containing multimetal layers. The procedure involves the use of heteroditopic and tritopic P,N ligands as connectors of the metal layers. The synthetic strategy is based on the ability of the latter ligands to react selectively with the metal complexes [AuCl(tht)] (tht: tetrahydrothiophene), [{RuCl(2)(p-cymene)}(2)] and [Pd(eta(3)-2-MeC(3)H(4))(cod)](OTf) (cod: 1,5-cyclooctadiene; OTf: triflate). In this way, metallodendrimers containing trimetallic Ru-Au-Pd or tetrametallic Ru-Au-Au'-Pd layers have been formed and characterized. The trimetallic dendrimer 9 can be selectively deconstructed by cleavage of the Ru-N or Au-N bonds by reaction with chloride or iodide salts, respectively.
