Hydrothermal reactions of lanthanide(III) chlorides with 4-HOOC-C(6)H(4)-CH(2)NHCH(2)PO(3)H(2) (H(3)L) at different ligand-to-metal (L/M) ratios afforded nine new lanthanide(III) carboxylate-phosphonates with two types of 3D network structures, namely, LnCl(HL)(H(2)O)(2) (Ln = Sm, 1; Eu, 2; Gd, 3; Tb, 4; Dy, 5; Er, 6) and [Ln(2)(HL)(H(2)L)(L)(H(2)O)(2)].4H(2)O (Ln = Nd, 7; Sm, 8; Eu, 9). Compounds 1-6 are isostructural and feature a 3D network in which the LnO(7)Cl polyhedra are interconnected by bridging CPO(3) tetrahedra into 2D inorganic layers parallel to the bc plane. These layers are further cross-linked by organic groups of the carboxylate-phosphonate ligands via the coordination of the carboxylate groups into a pillared-layered architecture. Compounds 7-9 are also isostructural and feature a 3D open-framework composed of 1D lanthanide(III) phosphonate inorganic slabs which are further bridged by organic groups of the carboxylate-phosphonate liagnds via the coordination of the carboxylate groups, forming large 1D tunnels along the b-axis which are filled by lattice water molecules. Luminescent measurements indicate that compounds 2, 4, and 5 show strong emission bands in red, green, and yellow light region, respectively. Magnetic properties of 2, 3, 5, and 7 have also been studied.
水热条件下，镧系元素(III)氯化物与 4-HOOC-C(6)H(4)-CH(2)NHCH(2)PO(3)H(2)（H(3)L）在不同配体与金属（L/M）比例下反应，生成了九种具有两种三维网络结构的新型镧系元素(III)羧酸膦酸盐，即 LnCl(HL)(H(2)O)(2)（Ln = Sm, 1；Eu, 2；Gd, 3；Tb, 4；Dy, 5；Er, 6）和[Ln(2)(HL)(H(2)L)(L)(H(2)O)(2)].4H(2)O（Ln = Nd, 7；Sm, 8；Eu, 9）。化合物 1-6 是同构的，具有三维网络结构，其中 LnO(7)Cl 多面体通过桥连的 CPO(3)四面体连接成平行于 bc 面的二维无机层。这些层通过羧酸膦酸盐配体的有机基团通过羧酸基团的配位进一步交联成一个支柱层状结构。化合物 7-9 也是同构的，具有由一维镧系元素(III)膦酸无机片组成的三维开放式骨架，这些无机片通过羧酸膦酸盐配体的有机基团进一步通过羧酸基团的配位桥接，形成沿着 b 轴的大的一维隧道，这些隧道被晶格水分子填充。发光测量表明，化合物 2、4 和 5 分别在红光、绿光和黄光区域显示出强发射带。化合物 2、3、5 和 7 的磁性性质也进行了研究。
