| 摘要: 水热条件下采用Nd2(CO3)3和草酸钠作为反应物合成出一个新的三维钕(Ⅲ)配位聚合物{[Nd2(ox)(cb)2(H2O)2]·3H2O}n(1)(ox=草酸,cb=碳酸),并分别用元素分析、红外光谱、差热分析、X-射线粉末衍射和X-射线单晶衍射等表征了该结构。晶体结构分析结果表明:μ2桥联的草酸根离子与μ4桥联的碳酸根离子将钕离子连接成三维微孔结构,沿b轴和c轴方向分别具有孔径大小为0.53nm×0.41nm和0.59nm×0.84nm的通道。拓扑分析结果表明化合物1为(4,5)连接类型。荧光分析表明常温固态下配合物1发射近红外荧光。 |

| Abstract: Aneodymium(Ⅲ) coordination polymer, namely, {[Nd2(ox)(cb)2(H2O)2]·3H2O}n (1) (ox=oxalate, cb=carbonate) (1), has been hydrothermally synthesized and characterized by elemental analysis, IR, TGA, powder X-ray diffraction, and single-crystal X-ray diffraction. Structural determination reveals that the neodymium ions are bridged by μ2-ox and μ4-cb ligands to give a 3D framework including 2D channels of 0.53 nm×0.41 nm along the b axis and 0.59 nm×0.84 nm along the c axis, respectively. It can also be described as a (4,5)-connected {44.62}{44.66} topological 3D framework. Solid-state 1 emits the intensely NIR characteristic luminescence of Nd3+ ion at room temperature. CCDC: 917863. |
