在水热条件下合成了四种同结构有机模板化的草酸磷镧系化合物（H(4)APPIP）[Ln(3)(C2O4)(5.5)(H2PO4)(2)]中心点5H(2)O （Ln = Er-Lu和APPIP = 1,4-双（3-氨基丙基）哌嗪），并用单晶和粉末x射线衍射对其进行了表征。它们的结构包含LnO(8)三角形十二面体，由三个双双齿草酸盐连接在（102）平面上形成层，由磷酸二氢和双单齿草酸盐配体连接形成三维框架。电荷补偿的四质子化1,4-二（3-氨基丙基）哌嗪阳离子和晶格水分子位于12元环直线型通道中。它们是有机模板化草酸磷酸镧系的第一个例子。研究了Er化合物的热稳定性、来宾脱附-吸附性能、原位变温粉末x射线衍射、磁化率和光致发光光谱以及Yb化合物对Biginelli反应的催化活性。
Four isostructural organically templated lanthanide oxalatophosphates, (H(4)APPIP)[Ln(3)(C2O4)(5.5)(H2PO4)(2)] center dot 5H(2)O (Ln = Er-Lu and APPIP = 1,4-bis(3-aminopropyl)piperazine), have been synthesized under hydrothermal conditions and characterized by single-crystal and powder X-ray diffraction. Their structures contain LnO(8) trigonal dodecahedra linked by three bis-bidentate oxalates to form layers in the (102) plane, which are connected by dihydrogen phosphate and bis-monodentate oxalate ligands to form a 3D framework. The charge-compensating tetraprotonated 1,4-bis(3-aminopropyl)piperazinium cations and lattice water molecules are located in the 12-membered ring straight channels. They are the first examples of organically templated lanthanide oxalatophosphates. The thermal stability, guest desorption-sorption properties, variable-temperature in situ powder X-ray diffraction, magnetic susceptibility, and photoluminescence spectrum of the Er compound and catalytic activity of the Yb compound for the Biginelli reaction have also been studied.
