【 摘 要 】

[Sm(H 2 O) 4 (NO 3 ) 3 ](4,4'-Hbipy) 2 (NO 3 ) 2( 1 ) (bipy = bipyridine) has been synthesized via hydrothermal reaction and characterized by X-ray diffraction. The title complex features an isolated structure, based on discrete 4,4'-Hbipy moieties, isolated nitrates and [Sm(H 2 O) 4 (NO 3 ) 3 ] species. The samarium ion is in a distorted bicapped square antiprism environment, coordinated by three bidentate nitrates and four coordination water molecules. The 4,4'-Hbipy moieties, isolated nitrates and [Sm(H 2 O) 4 (NO 3 ) 3 ] species are held together via hydrogen bonds and p…p interactions to form a 3-D supramolecular framework. Luminescent investigation reveals a strong emission in blue region. Optical absorption spectrum of1reveals the presence of an optical gap of 3.60 eV.                KEY WORDS : Bipyridine, Crystal structure, Fluorescence, Hydrothermal reaction, Samarium Bull. Chem.
