| dc.description.abstract | Transition metal (M = Co(II), Ni(II) and Cu(II)) complexes have been synthesized by refluxing the metal chloride with ligand, 2,2’–bipyridine .Tris(2,2’-bipyridine )complexes of cobalt(II), nickel(II), and copper(II) have been encapsulated within the supercage of zeolite − NaY by the reaction of exchanged metal ion and flexible ligand that diffuses into the cavities. The hybrid material obtained and neat metal complexes have been characterized by FTIR, elemental analysis (CHN), UV−vis, magnetic susceptibility, molar conductance measurements, cyclic Voltammetry, TGA and Inductive Coupled Plasma (ICP) techniques. Infrared spectra of the complexes revealed that higher frequency shifts of varying magnitudes were observed in the (C=N) and lower in the (C=C) aromatic stretching vibrations from their ligand values. TGA was used to analyze the principal volatile thermal decomposition (fragmentation) products of 2, 2-bipyridne complexes (encapsulated and neat).The TGA and CHN data of intrazeolite complexes in comparison to those of the neat complexes suggest that the insertion of small amount of organic molecules(2,2-bipyridine) into the pores of the zeolite. | en_US |
