Coordination Polymers of 4,4'-(8-Quinolinolyl-5-methylenoxy) Diphenyl Sulfide

Abstract

Coordination polymers containing a novel bis(oxine) bidentate ligand, namely 4,4'-[(8-Quinolinolyl-5-methylenoxy) diphenyl sulfide H₂L 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 4,4'-dihydroxy diphenyl sulfide in the presence of a base catalyst. 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 (M_n) 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
