Synthesis and characterization of Cr(III), Mn(III), Fe(III), Ti(III), YO(IV), Th(IV), Zr(IV) and UO<sub>2</sub>(VI) polychelates derived from bis-bidentate salicylaldimine Schiff base
322-326The polychelates of Cr(III), Mn(III), Fe(III),
Ti(III), YO(IV), Th(IV),
Zr(IV) and UO2(VI) with
4,4'-bis[(N-p-nitrophenylsalicylaldimine-5)-azolbiphenyl (BNSAB) have been
synthesized and characterized by elemental analysis, magnetic susceptibility,
electronic and IR spectral data and
thermogravimetric analysis. The ligand BNSAB acts as bis-bidentate ONNO donor.
The thermal data have been analyzed for the kinetic parameters by Broido's
method. The electrical conductivity of the ligand and polychelates has been
measured which indicate their semiconducting behaviour in the studied
temperature range. The ligand and its polychelates have also been screened for
their antimicrobial activity using various microorganisms
