| Abstract: Eleven novel rare earth complexes[RE(HPMαFP)2Pen(NO3)2]NO3((HPMαFP)2 Pen:N,N’ -bis[(1-phenyl-3-methyl-5-oxo-4-pyrazolinyl )α-furylmethylidyne]-o-phenylenediimine;RE =La,Pr,Nd,Sm,Eu,Tb,Dy,Ho,Er,Yb,Y)have been synthesized.They were characterized by IR,UV-visible,1H NMR,13C NMR,fluorescence,elemental analysis and molar conductance.The resu lts show that the bis-Schiff base ligand is quadridentate and the rare earth i ons are eight-coordinated in the complexes.The antibacterial ex periment indicated that they have hi gh antibacterial activities against S.aureus,B.subtillis,E.coli,E.carotovora and C.flaccumfaciens. |
