The carbonyl complex [OsII(NH3)5(CO)]2+ undergoes a photolysis in aqueous solution which yields [OsVI(NH3)4N]3+ (Φ=10-3 at λirr =255 nm) and methanol. This photoreduction of CO to CH3OH represents a novel type of photoreactivity of metal carbonyl c

The oxidation of methane to methanol takes place selectively by the photolysis of perrhenate in aqueous solution in the presence of methane. This photoreaction is formally an oxygen atom transfer. Because the reoxidation of the reduced perrhenate is

Astaxanthin (AXT) is a natural carotenoid which provides colorations to numerous living species such as salmon. Owing to its chelate function deprotonated astaxanthin (axt−) should be easily attached to metal ions. The complex RhIII(phpy)2(axt) wit

Osmocene is intrinsically photoactive. It photolyzes in n-hexane by a reductive elimination leading to the generation of metallic osmium. Moreover, both cyclopentadienyl anions as ligands in osmocene are oxidatively eliminated. Surprisingly, they are

The mercarbides C(HgX)4 with X− = Cl− and acetate− which are characterized by a tetrahedral (C4 −Hg2 +4)4 + core fragment show two absorptions in the UV spectral region at λmax = 234 nm and 270 nm. They are attributed to (C4 − → Hg2 +) L

The complexes RhIII(phpy)2(E∪O) with phpy− = deprotonated 2-phenylpyridine and E∪O− = bidentate anions of the biologically important compounds E∪O (troH = tropolone, flaH = flavonol and lumH = lumichrome) have been prepared and characterize

The setting of gypsum plaster can be monitored by luminescence rigidochromism. The progress of the setting process which is accompanied by hardening is indicated by a blue shift of the phosphorescence of a suitable water soluble rhenium complex. This

Coordination compounds, which simultaneously contain a reducing and an oxidizing ligand are frequently characterized by low-energy LLCT transitions. In suitable cases, CT interactions between such donors and acceptors may also occur in purely organic

Generally, metal-centered ff states dominate the discussion of the excited state properties of lanthanide complexes. In particular, the luminescence properties of Eu(III) and Tb(III) compounds have been studied in great detail for many decades. Howev

Peroxide is a reductant as well as an oxidant. It follows that O 2 2− as a ligand can serve as CT donor, but also as CT acceptor. In combination with oxidizing and reducing metals low-energy ligand-to-metal (LMCT) and metal-to-ligand (MLCT) transit
