We analyzed the properties and structures of the hydrogen-bonded complexes of tetrahydrofuran(THF) and water by means of experimental Raman spectra and ab initi
The biphenol based discrete ion-pair rare earth complexes,[Ln(EDBP)_2(DME)Na(DME)_3][Ln=Er(1),Yb(2), Sm(3)],were prepared and used as catalysts for the ring-ope
