Synthesis and characterization of manganese (III), iron (III), zirconium (IV), thorium (IV), oxovanadium (IV) and dioxouranium (VI) chelates of a polymeric schiff base (PSB)
1110-1113A few
symmetrical tetradentate polymeric schiff base (PSB) chelates of the type
[M(PSB)]n where M = Mn (III), Fe (III), Zr (IV), oxovanadium (IV),
Th (IV), dioxouranium (VI) and PSB is derived from 4, 4使-dihydroxy-3,3'-dipropylbiphenyl
and 1,3- diaminopropane, have been synthesised and characterized by elemental
analysis, magnetic moment, IR, electronic spectra and TGA studies. The D.C.
electrical conductivity and antimicrobial activities of ligand and the chelates
have also been studied. The thermal decomposition of the chelates occurs mainly
in two steps. Thermal activation energy has been determined by Broido method
