The reaction of 2-chlorobenzoic acid,5,5′-dimethyl-2,2′-bipyridine and Tb (NO3)3 ·6H2O under hydrothermal condition gave one new dinuclear terbium(Ⅲ) complex,Tb2 (2-cb)4(dmpy)2 (NO3)2 (1) (2-cb =2-chlorobenzoate,dmpy=5,5′-dimethyl-2,2′-bipyridine),which has been characterized by elemental analysis,IR,TGA and single-crystal X-ray diffraction.Complex 1 is a dinuclear terbium(Ⅲ) complex,which is further extended to a 2D layered network by C-H…O hydrogen bonding interactions.The results of thermal analysis indicate that complex 1 is quite stable up to 280 ℃.1 emits the intensely green characteristic luminescence of Tb3+ ion at room temperature,with lifetime of up to 431.8 μs.CCDC:865399.
