| Abstract | Described are the synthesis and characterization of Ru(II) complexes of the type RuCl2L2(N-O), where L-2 is either 1,4-bis(diphenylphosphino)butane (dppb) or (PPh3)(2), and N-O represents chelated 2-benzoylpyridine (2-bzpy) or 2-acetylpyridine (2-acpy); the Ru presursors used were [RuCl2(dppb)](2)(mu-dppb) or RuCl2(PPh3)(3). The crystal structure of cis-RuCl2(dppb)(2-bzpy) is presented, and three other RuCl2L2(N-O) complexes with cis-chlorines are isolated and characterized spectroscopically; of the trans-dichloro species, RuCl2(PPh3)(2)(N-O) complexes are isolated, while the corresponding dppb species are characterized in situ. In all cases, thermodynamically stable cis-complexes are formed from initially formed trans-species. |
