Abstract

An improved synthesis using microwave heating affords (CHPO(OCH)) in excellent isolated yield (95 %). The ligand properties of this bisphosphonateester were explored towards hard metal centers ( = Ca, UO) and ( = La, Ce, Sm, Eu) resulting in coordination polymers, for which the reduction of ionic size of the central metal atom resulted in lower-dimensional structural motifs as opposed to higher dimensional networks obtained for the larger ions. All coordination polymers were characterized by single-crystal X-ray diffraction, IR spectroscopy, and combustion analysis. The ligand was furthermore characterized with multinuclear NMR spectroscopy.

摘要

使用微波加热的改进合成方法以优异的分离产率（95%）得到(CHPO(OCH))。研究了这种双膦酸酯对硬金属中心（= Ca、UO）和（= La、Ce、Sm、Eu）的配体性质，得到了配位聚合物，其中中心金属原子离子尺寸的减小导致了低维结构单元，这与较大离子形成的高维网络相反。所有配位聚合物均通过单晶X射线衍射、红外光谱和燃烧分析进行了表征。此外，还用多核核磁共振光谱对该配体进行了表征。
