Cooridnation polymers containing a novel bis(oxine) bidentate ligand namely N,N' -di(8-hydroxyquinolinoly 1-5) -N,N' - diethyl-1,2-ethanediamine (QEED) have been prepared with the metal ions Zn(II), Cu(II), Ni(II), Co(II) and Mn(II). The novel bis (bidenate) ligand was synthesized by condensation of 5-chlorometyl-8-hydroxyquinoline hydrochloride with N,N'-diethyl-1,2 ethaanediamne in the presence of a base catalyses. All of these coordination polymers and the parent ligand were characterized by elemental analyses and IR spectra and diffuse reflectance spectral studies. The thermal stability and number-average molecular weight (Mn) of all of the coordination polyerms were determined by Theromgravimetric analyses and non-aquous conductrometric titrations, respectively in addition, all of the coordination polymers have been characterized by their magnetic suspectiblities.
