COORDINATION POLYMERS OF 1,6-BIS(8-HYDROXYQUINOLIN-5-YL)-2,5-DIOXAHEXANE
摘要:
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(bidentate) ligand (H2L) was synthesized by condensation of 5-chloromethyl-8-hydroxyquinoline hydrochloride with ethylene glycol in the presence of a base catalyst. 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 ((M) over bar (n)) of all of the coordination polymers were determined by thermogravimetric analyses and non-aqueous conductometric titrations, respectively. Besides this, all of the coordination polymers also have been characterized by their magnetic susceptibilities.
