Coordination Polymers of N, Nʼ-di-(8-Hydroxyquinolinolyl- 5-methyl)-N, N-diethyl-1,3-propane diamine (QEPD)
Coordination polymers containing a novel bis(oxine) bidentate ligand, namely N,Nʼ-di(8-hydroxyquinolinolyl-5-methyl)-N,Nʼ-diethyl-1,3-propane diamine (QEPD) have been prepared with the metal ions Zn(II), Cu(II), Ni(II), Co(II) and Mn(II). The novel bis-(bidentate) ligand was synthesized by condensation of 5-chloromethyl-8-hydroxyquinoline hydrochloride with N,Nʼ-diethyl-1,2- propane diamine in the presence of a base catalyses. All of these coordination polymers and the parent ligand were characterized by elemental analyses, IR spectral and diffuse reflectance spectral studies. The thermal stability and number- average molecular weights () of all of the coordination polymers were determined by thermogravimetric analyses and non-aqueous conductometric titrations, respectively. In addition, all of the coordination polymers have been characterized by their magnetic susceptibilities.
