摘要

Two uranyl-containing organic coordination polymers,(UO_2)_2(mu_2-OH)(pdc)_2 Zn(bpy)(Ac)_2(H_2O)9 (1) (H_2pdc=pyridine-2,6-dicar-boxylic 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 deg C,this material exhibits considerable adsorption capacity for water and methanol upon removal of the guest species in the microporous channels.
