Eleven new lanthanide oxalatophosphonate hybrids with a 2D layered structures, namely, [Ln(H(3)L)(C(2)O(4))]·2H(2)O (Ln = La-Dy, Er and Y, H(4)L = C(6)H(5)CH(2)N(CH(2)PO(3)H(2))(2)), have been synthesized under hydrothermal conditions and structurally characterized by X-ray single-crystal diffraction, X-ray powder diffraction, infrared spectroscopy, elemental analysis and thermogravimetric analysis. Compounds 1-11 are isomorphous and they exhibit a 2D framework structure. Two {LnO(8)} polyhedra and four {CPO(3)} tetrahedra are interconnected into a unit via corner-sharing, and the so-built units are bridged by the oxalate anions into a layer. The result of connections in this manner is the formation of a 24-atom window. The thermal stabilities and guest desorption-sorption properties of compounds 1-11 have been investigated. The luminescent properties of compounds 5, 6, 8 and 9 have also been studied.
11 种具有二维层状结构的新型镧系元素草酸盐膦酸盐杂化物，即[Ln（H（3）L）（C（2）O（4））]·2H（2）O（Ln=La-Dy，Er 和 Y，H（4）L=C（6）H（5）CH（2）N（CH（2）PO（3）H（2））（2）），在水热条件下合成，并通过 X 射线单晶衍射、X 射线粉末衍射、红外光谱、元素分析和热重分析进行了结构表征。化合物 1-11 是同构的，它们表现出二维骨架结构。两个{LnO（8）}多面体和四个{CPO（3）}四面体通过角共享连接成一个单元，所构建的单元通过草酸盐阴离子桥接到一个层中。这种连接方式的结果是形成了一个 24 原子的窗口。还研究了化合物 1-11 的热稳定性和客体脱附-吸附性能。还研究了化合物 5、6、8 和 9 的发光性能。
