Synthesis, Structure, and Fluorescent Study of Complex: bis(4,4′-dimethyl-2,2′-bipyridinato)-tris(nitrato-o,o’)-terbium(III)

Abstract

A novel complex, Tb(III)L₂(NO₃)₃ (L is 4, 4′-dimethyl-2, 2′-bipyridine), has been synthesized. Structural analysis was carried out on the basis of X-ray diffraction data, and the title complex is a mononuclear structure which crystallized in Orthorhombic, space group Aba2, with a=14.9374(17) Å, b=18.325(3) Å, c=10.0586(12) Å, α=ß=γ=90°, Z=4, D_c=1.721 Mg/m³, V=2753.3(6) Å⁻³. Exposed to ultraviolet radiation of 321 nm, the title complex produces strong green light, and it can be a prospective green light material.
