| Abstract: A terbium(Ⅲ) complex [Tb2(NO3)(DMPA)5(phen)2] (HDMPA=homoveratric acid, C12H12O4; phen=1,10-phenanthroline), was synthesized and characterized by elemental analysis, IR and TG-DTG. Its crystal structure was determined by single crystal X-ray diffraction method. The complex, C74H71N5O23Tb2, crystallizes in the monoclinic system, space group P21/n. The emission spectrum of complex, there are four main peaks, 489, 545, 584 and 622 nm, respectively, corresponding to 5D4→7F6, 5D4→7F5, 5D4→7F4 and 5D4→7F3 transitions of Tb(Ⅲ). The intensity of 5D4→7F5 is much stronger than others. CCDC: 729945. |
