  Synthesis and structural characterization of diene-and carbonyl-rhodium(I) complexes containing bridging adeninate ligands

  摘要：

  Diene- and dicarbonyl-rhodium(I) complexes [(diene)Rh(mu-BH-1)]2 (diene = cod, nbd) and [(CO)2Rh(mu-BH-1)]2 have been prepared by the reaction of [(diene)Rh(acac)] or [(CO)2Rh(acac)] with the adenine derivatives: adenine (AdH), N6-methyladenine (6MadH) and N6,N6-dimethyladenine (DmadH). These dimeric complexes exhibit N3, N9 coordination of the bridging adeninate ligands as demonstrated by an X-ray structural study of [(CO)Rh(mu-Dmad)(PPh3)]2 3c, prepared by substitution of a carbonyl ligand in [(CO)2Rh(mu-Dmad)]2 3b by PPh3. In contrast, a tetrameric structure was observed for [(CO)2Rh(mu-3madH-1)]4 4 (3mad = 3-methyladenine), in which the 3madH-1 anions are coordinated at N6 and N7. When N7 coordination is unfavourable and N9 unavailable, which is the case for 8-aza-9-methyladenine (Maad), N1, N6 binding may be observed, as established by an X-ray structural study of [(cod)Rh(mu-MaadH-1)]2 5. However, in order to achieve this coordination mode it necessary for the substituted exocyclic amino groups (N6) to twist by an average angle of 31.2-degrees out of the base plane.
