Abstract

Five novel metal pamidronates (3-ammonium-1-hydroxypropylidene-1,1-bisphosphonate, APD) formulated as Ni2(C3NH10P2O7)4.4H2O (1), M(C3NH9P2O7).H2O (M = Co (2), Mn (3), Zn (4)) and Cu3(C3NH8P2O7)2.2H2O (5) have been hydrothermally synthesized under similar conditions. Compound 1 is a molecular binuclear nickel cluster. Compounds 2 and 3 exhibit similar one-dimensional ladderlike structures. Compound 4 possesses a novel two-dimensional gridlike framework. Compound 5 shows an unusual three-dimensional architecture, in which two-dimensional layers with a parquet motif are pillared by {CuO4} planar squares. Different dinuclear secondary building units (SBUs) are observed in compounds 1-5, depending on the different coordination modes of APD. They also exhibit different photoluminescence properties.

摘要

在相似条件下通过水热法合成了五种新型金属帕米膦酸盐（3-铵基-1-羟基亚丙基-1,1-二膦酸酯，APD），其化学式分别为Ni2(C3NH10P2O7)4.4H2O (1)、M(C3NH9P2O7).H2O（M = Co (2)、Mn (3)、Zn (4)）和Cu3(C3NH8P2O7)2.2H2O (5)。化合物1是一种分子双核镍簇。化合物2和3呈现出相似的一维梯状结构。化合物4具有新颖的二维网格状骨架。化合物5展现出不同寻常的三维结构，其中具有镶木地板图案的二维层由{CuO4}平面正方形支撑。在化合物1 - 5中观察到不同的双核二级结构单元（SBUs），这取决于APD的不同配位模式。它们还表现出不同的光致发光性质。
