ランタンとガドリニウムのN,N'-ビス(1-アセトニルエチリデン)エチレンジアミン錯体の合成

抄録

The lanthanoid complexes with N, N'-bis(aceto nylethylide ne)ethylenediaine(AEH2)were synthesized by the new method using mixed olvent (methanol/acetone) at room temperature.The complexes were characterized by chemical analyses, IR spectra, and X-ray powder diffraction analyses. As to La and Gd complexes, these results were different from those reported by Dutt et al.2. La formed a different complex from other light rare earth complexes, La2(AEH2)sC16 2H20. Gd formed the same type of complex as light rare earth complexes, Gd(AEH2)2Cls. MetaNigand stretching vibrations were observed at 406A 429 cm-i. These absorption frequencies increased in the order of the atomic number of metal ions.
