Three new two-dimensional Cu(I)-Ln(III) heterometallic coordination polymers [Ln(III)Cu2(I)(Hbpdc)4] · Cl · xH2O [Ln(III) = La(III), x = 8 (1); Ln(III) = Pr(III), x=9 (2); Ln(III) = Eu(III), x = 8 (3)] (H2bpdc = 2,2'-bipyridyl-5,5'-dicarboxylic acid) have been prepared under hydrothermal conditions and structurally characterized by elemental analyses, inductively coupled plasma atomic emission spectrometry (ICP-AES) analyses, IR spectra, X-ray photoelectron spectroscopy (XPS) and single-crystal X-ray diffraction. X-ray diffraction indicates that the isomorphic 1-3 display the two-dimensional sheet structure constructed from Cu(I)(Hbpdc)2 fragments through Ln(3+) connectors. Moreover, the solid-state photoluminescence measurements of 3 indicate that the Eu(III) ions, Hbpdc(-) ligands and Cu(I) cations make contributions to its luminescent properties simultaneously.
三种新的二维 Cu(I)-Ln(III) 异金属配位聚合物 [Ln(III)Cu2(I)(Hbpdc)4]·Cl·xH2O [Ln(III) = La(III), x = 8 (1); Ln(III) = Pr(III), x=9 (2); Ln(III) = Eu(III), x = 8 (3)]（H2bpdc = 2,2'-联吡啶-5,5'-二羧酸）在水热条件下制备，并通过元素分析、电感耦合等离子体原子发射光谱 (ICP-AES) 分析、IR 光谱、X 射线光电子能谱 (XPS) 和单晶 X 射线衍射进行结构表征。X 射线衍射表明，同构的 1-3 通过 Ln(3+) 连接体展示出由 Cu(I)(Hbpdc)2 片段构建的二维片状结构。此外，3 的固态光致发光测量表明，Eu(III) 离子、Hbpdc(-) 配体和 Cu(I) 阳离子同时对其发光性能做出贡献。
