Crystal Structure and Magnetic Characteristics of Novel Neutral Lanthanide(Ⅲ)- Nitronyl Nitroxide Radical Complexes

【摘要】：正Three novel rare-earth complexes based on a new nitronyl nitroxide radical have been synthesized and characterized by single-crystal X-ray diffraction,with formula{[Ln(hfac)_3(NITPh Br F)2]·CH_2Cl_2}(Ln=Gd(1),Tb(2),Dy(3);hfac=hexafiuoroacetylacetonate;NITPhB rF=2-(5-bromo-2-fluorophenyl)-tetramethylimidazoline-1-oxyl-3-oxide).These compounds are isostructural,which crystallize in the monoclinic
