Kurzfassung:
Linking three nucleobases by two metal ions M of linear coordination geometry leads to metal-modified base triples. With M = trans-(amine) 2 Pt II , the bases are forced into an essentially coplanar fashion with interbase H bonding maintained in many cases. The model nucleobase triples described here are of general composition {[trans-(amine) 2 PtB] 2 (9-MeA)} n+ with two nucleobases B bound via Pt to N1 and N7 of 9-methyladenine (9-MeA). The X-ray structure of a precursor, ([trans-(CH 3 H 2 ) 2 PtCl] 2 (9-MeA)}(ClO 4 ) 2 , is briefly described. The generation of metalated, cyclic nucleobase quartets and their expected structures are discussed and ways towards larger macrocyclic metal compounds are pointed out.
