Coordination Polymers of N,N’-Di-(8-hydroxyquinolinolyl-5- methyl)-N,N’-dimethyl-1,3-propane diamine (QMPD)

Coordination polymers containing a novel bis(oxine) bidentate ligand, namely N,N’-di(8- hydroxyquinolinolyl-5-methyl)-N,N’-dimethyl-1,3-propanediamine (QMPD) have been prepared with the metal ions Zn (II), Cu (II), N i(II), Co (II), and Mn (II). The novel bis- (bidentate) ligand was synthesized by condensation of 5-chloromethyl-8-hydroxyquinoline hydrochloride with N, N’-dimethyl-1,3-propanediamine in the presence of a base catalyses. All of these coordination polymers and the parent ligand were characterized by elemental analyses and IR spectral and diffuse reflectance spectral studies. The thermal stability and number- average molecular weights (Mn) 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
