“…During the last several decades, a broad variety of dimetal paddle-wheel (PW; M 2 n + , n = 4–6) complexes and supramolecular structures containing equatorial and axial ligands have been synthesized and characterized. − In particular, redox-active compounds with well-defined spectroscopic and electrochemical properties have attracted considerable interest in the exploration of potential applications as molecular wires and devices. − Therefore, particular attention has been paid to structural, spectroscopic, and electrochemical factors to develop novel electronic materials, e.g., molecular wires, sensors, etc. − The group of Cotton synthesized a variety of redox-active Fc-containing Mo 2 (Fc = ferrocenyl) complexes equatorially bridged by −COO units, revealing no obvious electronic coupling between cis-positioned Fc units. − Later, Ren’s group published work on Fc-containing Ru 2 compounds bridged by either equatorial or axial linkers (i.e., −COO, alkynyl), executing detailed spectroscopic and electronic studies on the dimetal compounds. − On the basis of the results published so far, conclusions on electronic communication with regard to structural motifs can be drawn (Figure ).…”

Three novel cis-to-trans-converted dimolybdenum(II) complexes, trans-[Mo2(O2C-Fc)2(DPPX)2][BF4]2 {2a-2c; DPPX = DPPA [N,N-bis(diphenylphosphino)amine], DPPM [1,1-bis(diphenylphosphino)methane], and DPPE [1,2-bis(diphenylphosphino)ethane], respectively}, were synthesized through the insertion of bulky diphosphine ligands, which force a permanent trans arrangement, as evidenced by X-ray crystallography and density functional theory calculations. All compounds were characterized by means of NMR, UV-vis, and IR spectroscopy as well as thermogravimetry-mass spectrometry measurements. Interestingly, uncommon UV-vis transitions and oxidation sequences were observed compared to previously reported ones. As verified by electrochemical measurements, all synthesized complexes show two separate one-electron-redox processes assigned to subsequent oxidations of the two redox-active ferrocenecarboxylate ligands, with a split of ca. 70 mV. This behavior reveals electronic interaction between the two equatorially trans-positioned ferrocenyl units. The presented work provides new insights into the rational synthesis of electronically coupled trans-coordinated Mo2 systems, paving the way toward the design of linear multicenter redox-active oligomers.

“…The ability of the metal-metal bonded Ru 2 n+ unit to stabilize multiple oxidation states with n = 4, 5, 6 has inspired the deliberate synthesis of compounds with two or more Ru 2 units linked together through their equatorial or axial sites (Scheme 1). [4][5][6][7][8][9][10][11][12][13][14][15] To our knowledge, all of the currently reported bridging units between Ru 2 centers are organic linkers. Herein we present the first example of a tri-cationic dimeric Ru 2…”

The complex {[Ru2(ap)4]2[AgF2]}[BF4]3 ({2}[BF4]3, ap = 2-anilinopyridine), containing the [AgF2](-) anion ligated to two [Ru2](6+) cores, is prepared, characterized, and compared to dimeric dumbbell-type structures, monomeric Ru2 structures, as well as the known set of dihalo coinage-metalate anions. X-ray crystallography indicates that the Ru-Ru and Ru-F distances are rather short, 2.2835(3) Å and 2.054(1) Å, respectively, while the Ag-F distance of 2.274(1) Å is longer than that calculated for the free/un-ligated anion. Cyclic voltammetry in dichloromethane indicates that, while some of {2}(3+) breaks apart into an [Ru2(ap)4F](+) ([3](+)) monomer in solution, the remaining dimer has a single reversible two-electron redox feature for the Ru2(6/5+) couple that is at a lower potential than that of [3](+). This is one of the few examples of a ligated dihalo coinage-metalate, and it is the first example of a coinage metal difluoride anion, either free or ligated.

Supramolecular assemblies of multi-nuclear transition metal complexes: Synthesis and redox properties

The synthetic features of supramolecular assemblies comprised of multi-nuclear transition metal complexes were reviewed by classification of the reaction patterns: (1) substitution reaction by bridging ligands, (2) substitution reaction by monodentate ligands, and (3) coupling reaction of functional groups attached to peripheral ligands. Architectural control for assembling multinuclear units is difficult because of the complicated ligand substitution reactions of metal clusters; but controlled ligand substitution of multi-metallic complexes recently became a targeted subject of coordination chemistry by introducing suitable bridging and monodentate ligands to keep multimetallic entities intact, leading to the formation of 1D, 2D, and 3D supramolecules of multimetallic units. Another synthetic protocol is aimed at transition metal-catalyzed coupling reactions of peripheral ligands that provide selective oligomerization of multi-metallic complexes. These supramolecules are of particular interest because of their unique redox properties centered at multi-metallic units, and their redox behaviors are described.
