Electron localization dynamics in the triplet excited state of [Ru(bpy)3]2+ in aqueous solution.
These studies reveal a solvent-induced breaking of the coordination symmetry with consequent localization of the photoexcited electron on one or two bipyridine units for the entire length of the simulation, which amounts to several picoseconds.
Synthesis and characterization of organometallic ionic liquids and a heterometallic carbene complex containing the chromium tricarbonyl fragment
Direct reaction between [Cr(CO)6] and arenes with ionic substituents affords the corresponding arene-chromium tricarbonyl complexes, [Cr(CO)3(arene)], in only modest yield. In contrast, these…

The title compound, [(C2H5)4N][FeCl4], has at room temperature a disordered structure in the high-hexagonal space group P63mc. At 230 K, the structure is merohedrally twinned in the low-hexagonal…
Heterolytic H2 Cleavage and Catalytic Hydrogenation by an Iron Metallaboratrane.
Reversible, heterolytic addition of H2 across an iron-boron bond in a ferraboratrane with formal hydride transfer to the boron gives iron-borohydrido-hydride complexes. These compounds catalyze the…
Terminal iron dinitrogen and iron imide complexes supported by a tris(phosphino)borane ligand.
Adaptable metallaboratranes: A tris- (phosphino)borane ligand stabilizes both low-valent Fe-N_2 complexes and a mid-valent imido species with a Fe≡NAr bond, thanks to its ability to shuttle between…
N2 functionalization at iron metallaboratranes.
The flexibility of the Fe-B linkage is thought to play a key role in these transformations of Fe-bound dinitrogen.

This sequence models the final steps of proposed Fe-mediated nitrogen fixation pathways and the five-coordinate trigonal bipyramidal complexes described are unusual in that they adopt S = 3/2 ground states and are prepared from a four- coordinate, S =3/2 trigonal pyramidal precursor.
Rhenium-Catalyzed Dehydration and Deoxydehydration of Alcohols and Polyols: Opportunities for the Formation of Olefins from Biomass
In view of the depletion of petroleum oils, new synthetic routes for the sustainable production of chemicals, fuels, and energy from renewable biomass sources are currently widely investigated. In…
A Ru(I) metalloradical that catalyzes nitrene coupling to azoarenes from arylazides.
Together, these studies show that 5-OMe is likely uninvolved in the catalytic cycle and demonstrates the influence of the metal center on the mechanism of reaction.
Interaction of organoplatinum(II) complexes with monovalent coinage metal triflates.
A series of homo- and heteroleptic complexes which were characterized by X-ray diffraction for organoplatinum(II) complexes binds to the coinage metals through short, ligand-unsupported d-d(10) contacts that are best described as Pt-->M dative bonds.
