A series of 12 inorganic-organic hybrid 4f-substituted arsenotungstates decorated with 3d-based complexes along with acetate bridging, viz. {[Cu(HO)(1,10-phen)(μ-CHCOO)][Ln(HO)(μ-CHCOO)(α-AsWO)]} (Ln = Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu), have been synthesized. These compounds were isolated using a one-pot synthetic strategy with copper, lanthanoid, trilacunary arsenotungstate and 1,10-phenanthroline as precursors. They were characterized using various analytical techniques, such as single-crystal X-ray diffraction (SC-XRD), powder XRD (PXRD), Fourier transform IR (FT-IR) spectroscopy, UV-Vis spectroscopy and thermogravimetric analysis (TGA). In all these compounds, a dinuclear Ln(ac) moiety is sandwiched between two monolacunary [AsWO] polyoxometalates (POMs), where the Ln(ac) moiety is comprised of two acetate ligands in a μ-κO,O':κO fashion. Moreover, the anion is decorated by a copper-phenanthroline-acetate complex through a terminal O atom of the polyanion.
通过乙酸根桥连修饰了一系列12种带有3d基配合物的无机-有机杂化4f取代砷钨酸盐，即{[Cu(HO)(1,10-菲咯啉)(μ-CHCOO)][Ln(HO)(μ-CHCOO)(α-AsWO)]}（Ln = Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb和Lu），并已合成出来。这些化合物是使用一锅合成策略，以铜、镧系元素、三缺位砷钨酸盐和1,10-菲咯啉作为前体分离得到的。它们使用各种分析技术进行了表征，如单晶X射线衍射（SC-XRD）、粉末XRD（PXRD）、傅里叶变换红外（FT-IR）光谱、紫外-可见光谱和热重分析（TGA）。在所有这些化合物中，双核Ln(ac)部分夹在两个单缺位[AsWO]多金属氧酸盐（POMs）之间，其中Ln(ac)部分由两个以μ-κO,O':κO方式存在的乙酸根配体组成。此外，阴离子通过多阴离子的一个端基O原子被铜-菲咯啉-乙酸根配合物修饰。
