| 摘要: 水热条件下采用Tb(NO3)3·6H2O，2-氯苯甲酸和5，5′-二甲基-2，2-联吡啶作为反应物合成出一个双核铽金属配合物Tb2(2-cb)4(dmpy)2(NO3)2（2-cb=2-氯苯甲酸，dmpy=5，5′-二甲基-2，2′-联吡啶）(1)，并分别用元素分析，红外光谱图，差热分析和X-射线单晶衍射等表征了该结构。晶体结构分析结果表明：化合物1为双核铽(Ⅲ)配合物，通过分子间的C-H…O氢键作用，双核分子进一步被连接成二维平面结构。热稳定性表明化合物1能够稳定到280 ℃；荧光分析表明常温固态下配合物1发射绿色荧光, 荧光寿命为431.8 μs。 |

| Abstract: 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. |
