By introduction of 1,4-benzenedicarboxylic acid as the second organic ligand, a series of novel lanthanide carboxyphosphonates with a 3D framework structure, namely, [Ln3(H2L)(HL)2(bdc)2(H2O)]·7H2O (Ln = La (1), Ce (2), Pr (3), Nd (4), Sm (5), Eu (6), Gd (7), Tb (8); H3L = H2O3PCH2NC5H9COOH; H2bdc = HOOCC6H4COOH) have been synthesized under hydrothermal conditions. Compounds 1–8 are isostructural and
通过介绍 1,4-苯二甲酸作为第二种有机配体,一系列具有3D骨架结构的新型镧系元素羧基膦酸酯,即[Ln 3(H 2 L)(HL)2(bdc)2(H 2 O)]·7H 2 O(Ln = La (1),Ce(2),Pr(3),Nd(4),Sm(5),Eu(6),Gd(7),Tb(8); H 3 L = H 2 O 3 PCH 2 NC 5 H 9 COOH; H 2 bdc = HOOCC 6 H 4COOH)是在水热条件下合成的。化合物1-8具有同构结构,并具有3D骨架,其中Ln(III)多面体通过将CPO 3 }四面体桥接到平行于ab平面的2D无机层中而相互连接。H的有机基团2大号-接枝上的层的两侧。这些层通过bdc 2-配体从一层到另一层的Ln原子进一步交联,形成具有沿a轴的一维通道系统的柱状结构。已经研究了化合物1–8的热稳定性。化合物的发光特性5-8,化合物8的磁性也已经研究过。
