Preparation and Characterization of Complexes of 4'-Bromo-5'-Nitrobenzo-15-Crown-5 with Rare Earth(Ⅲ)
Abstract:
The complexes of 4'-bromo-5'-nitrobenzo-15-crown-5(L) with rare earth have been synthesized and characterized by elemental analysis, IR, UV, TG-DTA, molar conduc-tance and X-ray powder diffration analyses. The complexes have compositions of RE(NO3)3·L(RE=La~Nd), Sm(NO3)3·L·H2O and Eu(NO3)3·L·CH3CN·4H2O respectively with the coordination number of the rare earth cation in the complexes for La,Ce,Pr,and Nd being eleven. In the complexes with samarium and europium the crown ethers are coordi-nated with Sm3+ or Eu3+ via water molecules.
