A rare earth-organics complex [Tb2(C12H6O4N2)3(Phen)2(H2O)2·6H2O]n
(1)with 2, 2′-hi- pyridine-3, 3′-dicarboxylic acid (H2L) as the ligand has been synthesized and characterized by single-crystal X-ray structure determination. The fluorescent and magnetic properties of complex 1 were investigated. The results show that 1 has four characteristic emission peaks arising from the transition of terbium (Ⅲ) ion as ^5D4→^7F6 (490. 0 nm), ^5D4→^7F5 (546.0 nm), ^5D4→^7F4 (586.0 nm) and ^5D4→^7F3 (620.0 nm). The magnetic behavior shows that 1 exhibits weak antiferromagnetic property at low temperatures.
