Multinuclear Metal Nucleobase Complexes

Multinuclear Metal Nucleobase Complexes

Of all properties of metal nucleobase complexes, formation of multinuclear species appears to be an outstanding feature. After a brief introduction into well known polymeric metal nucleobase complexes, three aspects recently Studied in our laboratory will be dealt with in more detail: (i) Heteronuclear complexes derived from trans-[(amine)(2)Pt(1-MeC)(2)](2+) (1-MeC=1-methylcytosine). They form...

Multinuclear metal-binding ability of a carotene

Carotenes are naturally abundant unsaturated hydrocarbon pigments, and their fascinating physical and chemical properties have been studied intensively not only for better understanding of the roles in biological processes but also for the use in artificial chemical systems. However, their metal-binding ability has been virtually unexplored. Here we report that β-carotene has the ability to ass...

On Metal-Modified Nucleobase Triples and Quartets

frans'-Diamineplatinum(II), Nucleobases, 9-Methyladenine, Synthesis, X-Ray Linking three nucleobases by two metal ions M of linear coordination geometry leads to metal-modified base triples. With M = mzns-(amine)2Ptn, the bases are forced into an essen­ tially coplanar fashion with interbase H bonding maintained in many cases. The model nucleo­ base triples described here are of general composi...

Dinitrogen Binding and Cleavage by Multinuclear Iron Complexes

The iron-molybdenum cofactor of nitrogenase has unprecedented coordination chemistry, including a high-spin iron cluster called the iron-molybdenum cofactor (FeMoco). Thus, understanding the mechanism of nitrogenase challenges coordination chemists to understand the fundamental N2 chemistry of high-spin iron sites. This Account summarizes a series of studies in which we have synthesized a numbe...
