Abstract: | It synthesised the scbJff base lanthanide complexes {M(NO3)2]·2H2O;M=La,Nd,Sm}by N, N' - bis (salicylaldehyde - o - phenylenediamine) (Li ligand with rare earth metal salts.The corresponding complexes were chamctered with infrared spectroscopy (IR),IN- visible spectroscopy (IN),thermal weight (TG/DTA) and molar conductivity. The results showed that six coordinate bonds were contained between rare earth element complexes,and a pair of NO3- was coordinated with coordination central rare earth ion. |
