摘要Five novel rare earth complexes RE(2)(NO3)(6)L(2) . nH(2)O have been synthesized, where L=1,5-bis(1'-phenyl-3'-methyl-5'-pyrazolone-4')-1-(4'-aminobutane-1'imino)-5-pentaone, a new polydentate ligand containing beta-diketone, Schiff-base and NH2 groups, RE=Sin, Eu, Gd, Dy, Ho. They were characterized by elemental analysis, mass spectra(FAB), FTIR, micro FTIR, variable temperature FTIR and extended X-ray absorption fine structure(EXAFS). The results indicate that the complexes are dimer. There are three types of NO3- ions in the complexes, mono and didentate ligands and just anion as banlance ion. The C=O, C=N and NH2 groups all coordinated to rare earth. The coordination number is ca. eight. Two nitrogen and six oxygen atoms make up two coordinate layers. The ranges RE-N is around 0.230 similar to 0.240 nm and RE-O 0.240 similar to 0.250 nm. The preliminary results of bioassay show that the compounds have fungicidal activities and can regulate the growth of plants, Some complexes have cardiovascular activities in vitro.
