Tb (mMBA) 3Phen] · H 2 O was synthesized from ethanol solution with terbium m-toluate and 1,10-phenanthroline, where mMBA = m-toluate and Phen = Phenanthroline.The crystal structure of the complex was determined by X-ray diffraction, and the crystal consisted of the binuclear molecules of the title compound, one Tb10 + 1,10-phenanthroline molecule and one bidentate carboxylate Acid and 4 bridge carboxylate coordination, it is 8. In the complex carboxylate and terbium ions have two kinds of bonding mode chelating bidentate and bridging bidentate. At room temperature to obtain the coordination The excitation and emission spectra show that the complex emits very strong green fluorescence when excited by ultraviolet light, and the thermal analysis shows that the complex has good thermal stability.
