在水热条件下,成功合成了一例新的Cu-La异金属修饰的有机-无机杂化型多金属磷钨酸簇合物[Cu(dap)_2]_(3.5)[Cu(dap)_2(H_2O)]_2[La(α-PW_(11)O_(39))_2]·6H_2O(1)(dap=1,2-丙二胺),并通过元素分析、红外光谱、热分析和X射线单晶衍射对化合物进行了表征和研究.结构分析表明在化合物1中,单稀土取代的二聚[La(α-PW_(11)O_(39))_2]~(11-)单元之间通过[Cu(dap)_2]~(2+)阳离子连接,形成一维Z字型链状结构.值得注意的是,化合物1是首例一维含1,2-丙二胺有机配体Cu-La异金属修饰的磷钨酸簇合物.
A new Cu-La heterometallic modified organo-inorganic hybrid polyphosphotungstic acid cluster [Cu (dap) _2] _ (3.5) [Cu (dap) _2 (H_2O)] _2 [La (α-PW_ (11) O_ (39)) _2] · 6H_2O (1) (dap = 1,2-propanediamine) was determined and characterized by elemental analysis, infrared spectroscopy, thermal analysis and X The structure and properties of the compounds were characterized by X-ray diffraction and X-ray single crystal diffraction. The structural analysis showed that the single rare earth substituted dimeric [La (α-PW_ (11) O_ (39)) _2] ~ (11-) Through the [Cu (dap) _2] ~ (2+) cation to form a one-dimensional zigzag chain structure.It is noteworthy that compound 1 is the first one-dimensional 1,2-propanediamine organic ligand Cu -La heterometallated phosphotungstic acid cluster.
