Abstract
Two uranyl-containing organic coordination polymers, (UO 2) 2( μ 2-OH)(pdc) 2 Zn(bpy)(Ac) 2(H 2O) 9 ( 1) (H 2pdc = pyridine-2,6-dicarboxylic acid, bpy = 4,4′-bipyridine, HAc = acetic acid) and UO 2(pdc)(H 2O) ( 2) have been prepared through a hydrothermal route and characterized by single-crystal X-ray diffraction, thermogravimetric analyses (TGA) and adsorption measurement 1 possesses infinite water cluster chains, which play an important role in the stabilization of the crystal structure. Whereas compound 2 is thermally stable up to at least 350 °C, this material exhibits considerable adsorption capacity for water and methanol upon removal of the guest species in the microporous channels.
