Abstract
Nanosized mixed ligand Mn(II), Co(II), Cu(ІІ), Cd(II) and Pb(ІІ) coordination polymers derived from 1,3-di (4-pyridyl) propane (DPP) and benzimidazole (BIMZ) were synthesized. The compounds were characterized by elemental analysis, FT-IR and electronic spectral studies. The thermogravimetry (TG), derivative thermogravimetry (DTG) and differential thermal analysis (DTA) were used to study the thermal decomposition steps. The scanning electron microscope SEM photographs and particle size calculations from the powder XRD data indicate the nano-sized nature of three compounds prepared under ultrasonic irradiation (average size 20-34nm).
Keywords: Nano-structure, coordination polymers, XRD, SEM, thermal studies
