  Novel [Ru(polypyridine)(CO)2Cl2] and [Ru(polypyridine)2(CO)Cl]+-type complexes: Characterizing the effects of introducing azopyridyl ligands by electrochemical, spectroscopic and crystallographic measurements

  摘要：

  The reaction of ruthenium carbonyl polymer ([Ru(CO)(2)Cl-2](n)) with azopyridyl compounds (2,2'-azobispyridine; apy or 2-phenylazopyridine; pap) generated new complexes, [Ru(azo)(CO)(2)Cl-2] (azo = apy, pap). [Ru(apy)(CO)(2)Cl-2] underwent photodecarbonylation to give a chloro-bridged dimer complex, whereas the corresponding pap complex ([Ru(pap)(CO)(2)Cl-2]) was not converted to a dimer. The reactions of the chloro-bridged dimer containing the bpy ligand (bpy = 2,2'-bipyridine) with either apy or pap resulted in the formation of mixed polypyridyl complexes, [Ru(azo)(bpy)(CO)Cl](+). The novel complexes containing azo ligands were characterized by various spectroscopic measurements including the determination of X-ray crystallographic structures. Both [Ru(azo)(CO)(2)Cl-2] complexes have two CO groups in a cis position to each other and two chlorides in a trans position. The azo groups are situated cis to the CO ligand in [Ru(azo)(bpy)(CO)Cl](+). All complexes have azo N-N bond lengths of 1.26-1.29 angstrom. The complexes exhibited azo-based two-electron reduction processes in electrochemical measurements. The effects of introducing azopyridyl ligands to the ruthenium carbonyl complexes were examined by ligand-based redox potentials, stretching frequencies and force constants of CO groups and bond parameters around Ru-CO moieties.

  溶剂介导的完整反式-到-顺式异构化的[Ru（聚吡啶）（CO）2氯2 ]配合物

  摘要：

  在没有超强酸或还原剂的情况下，将反式（Cl）-[Ru（聚吡啶）（CO）2 Cl 2 ]配合物完全异构化为相应的顺式（Cl）-异构体。X射线晶体学用于确定所制备的顺式异构体的分子结构。光谱，结构和计算研究表明，异构化是通过乙氧羰基中间体（{Ru–C（O）OC 2 H 5 } +），这是通过溶剂乙醇与末端羰基配体的反应形成的。发现该络合物中二齿配体的电子效应对异构化具有重要影响。机理研究和异构化结果将使新型钌配合物的有效合成成为可能。
