Coordination polymers of 1,6-bis(8-hydroxyquinolin-5-yl)-2,5-dioxahexane

Coordination polymers of a novel bis(oxine) bidentate ligand namely 1,6-bis (8-hydroxyquinolin-5-yl)-2.5-dioxahexane (H2L) have been prepared with the metal ions Zn(II). Cu(II), Ni(II), Co(II) and Mn(II). The novel bis(bidenta te) ligand (H2L) was synthesized by condensation of 5-chloromethyl-8-hydrox yquinoline hydrochloride with ethylene glycol in the presence of a base cat alyst. All of these coordination polymers and the parent ligand were charac terized by elemental analyses, IR spectral and diffuse reflectance spectral studies. The thermal stability and number-average molecular weights ((M) o ver bar (n)) of all of the coordination polymers were determined by thermog ravimetric analyses and non-aqueous conductometric titrations, respectively . Besides this, all of the coordination polymers also have been characteriz ed by their magnetic susceptibilities.
