| Description | A series of binuclear complexes of a general formula [(dppbO2)Ln(NO3)3(l-dppbO2)Ln(NO3)3(dppbO2)] (Ln = Pr (1), Nd (2), Sm (3), Dy (4), Lu (5)) were prepared by reacting bis(diphenylphosphino)butane dioxide (dppbO2) with lanthanide nitrates under solvothermal conditions. All compounds were characterized by analytical and spectroscopic techniques, such as infrared spectroscopy and mass spectrometry with electrospray ionization, and their molecular structures were determined by single crystal X-ray diffraction analysis in four cases. In contrast to the majority of lanthanide complexes with bis(diphenylphosphino)ethane dioxide which were previously reported as 2D polymeric networks, the present compounds are strictly molecular. This is evidently manifestation of the longer and flexible ligand backbone that allows a chelating binding mode. |
