  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.

  The mixed bridged diene-rhodium(I) complex ([cod)Rh(μ-Cl)(μ-OAc)Rh(cod)] (1) has been prepared by the reaction of equivalent quantities of [(cod)RhCl]2 and potassium or sodium acetate at reflux in methanol. 1 exhibits an Rh…Rh distance of 3.161(1) Å. Reaction of 1 with N6,N6-dimethyladenine (DmadH) yields [(cod)Rh(DmadH)Cl] (2), and [(cod)Rh(μ-Dmad)]2 (3), which show N3 and N3,N9 metal binding, respectively

  通过等量的[（cod）RhCl] 2反应制备了混合的桥联二烯-铑（I）络合物（[cod）Rh（μ-Cl）（μ-OAc）Rh（cod）]（1）。和乙酸钾或乙酸钠在甲醇中回流。1显示的Rh…Rh距离为3.161（1）Å。1与N 6的反应，N 6-二甲基腺嘌呤（DmadH）产生[（cod）Rh（DmadH）Cl]（2）和[（cod）Rh（μ-Dmad）] 2（3），显示N3和N3，N9分别与金属结合。相反，1与8-氮杂9-甲基腺嘌呤（Maad）的反应仅产生一种二聚体[[cod）Rh（μ-MaadH -1）Rh（cod）Cl]。在图2（4）中，核碱基是三齿的，其中N1，N6和N7为铑结合位点。的结构1，2和4已经通过X射线结构分析确定。与N1键合的4中的铑原子与相关核碱基的平面相距1.08Å。
