摘要

Metal polychelates of the type [ML.(2H(2)O)X]Y where M = Cr-III, Mn-III, Fe-III, Ti-III, Zr-IV, VOIV, MoO2VI, UO2VI; X = H2O, Y = Cl with 4,4'-bis[(I-propanesalicylaldimine-5)azo]biphenyl (L) have been synthesized. Their structures have been proposed on the basis of elemental analysis, magnetic susceptibility measurements, IR and diffuse reflectance spectra and thermogravimetric analyses. H-1 NMR spectrum of the ligand clearly indicates the presence of OH and azoniethine groups. The polychelates are dark colored and insoluble in comnion organic solvents. Their thermograms showed the loss of water of hydration in first step followed by decomposition of ligand molecule. The thermal data have also been analyzed for the kinetic parameters using Horowitz-Metzger method. The electrical conductivity of ligand and its polychelates showed semiconducting behavior. All the polychelates were found to be active against a variety of bacteria.
