Abstract
New water soluble {CpRu} complexes with formula [RuCpX(L1)(L2)]n+ (L1, L2=PPh3, mTPPMS (meta-triphenyphsphine monosulfonate), PTA (1,3,5-triaza-7-phosphaadamantane), mPTA (N-methyl-1,3,5-triaza-7-phosphaadamantane)) were synthesized and characterized by elemental analytical, IR and NMR spectroscopy. Complexes [RuClCp(PPh3)(mPTA)](OTf) (3·OTf), [RuCpI(PPh3)(mPTA)]·2I·EtOH (5·I·EtOH)·and [RuCpBr(PTA)2]·3.5H2O (6·3.5H2O) were also characterized by single crystal X-ray diffraction. The NMR spectra of the complexes are in agreement with their composition, indicating also that their solid state structure is maintained in solution. These results are integrated in a thorough overview of preparative routes, structural composition and solubility of {CpRu} complexes containing water-soluble phosphanes.
