Syntheses, Characterization and Bacteriostatic Activities of 1-Phenyl-3-methyl-4-benzoylpyrazolone-5-thiosemicarbazone and Its Rare Earth Complexes
Abstract:
Title compound, a novel ligand, has been synthesized.Its thirteen rare earth complexes have been prepared by reacting the ligand with RE(OH)3 in ethanol-water(1:1) solution.The compositions of the complexes have been determied as REL3·nH2O(RE=La, Pr, Nd, Sm,Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu; n=4~6).The compounds have been characterized by elemental analysis, molar conductivity, IR, UV, 1H NMR and DTA-TG measurements.The ligand and complexes have been evaluated for bacteriostatic activity against Escherichia Coil,Staphpococcus aureus and Bacillus subtilis.
