A new mononuclear Dy(III) complex, namely {[Dy(tbpy)2(NO3)(DMF)]⋅DMF} (1) (tbpy=6-(tetrazol-5-yl)-2,2′-bipyridine, DMF=N,N-dimethylformamide), has been synthesized and characterized. Structural measurements reveal that the Dy(III) ion displays a distorted tricapped trigonal prism with two mono-anionic tridentate chelating ligands, nitrate anion and N,N-dimethylformamide molecule. Magnetic investigation indicates that the title complex 1 exhibits field-induced single-ion magnet behavior. Moreover, the studies on photoluminescence properties show that complex 1 displays relatively strong fluorescent emission, which are typical narrow emission bands of lanthanide ion. A new mononuclear Dy(III) complex based on bipyridyl-tetrazolate ligand has been synthesized and characterized. The title complex displays field-induced single-ion magnet behavior and relatively strong fluorescent emissions.
