摘要
利用微波加热改进合成后，(C6H4PO(OCH3)2)2 的分离产率极高（95%）。研究人员探索了这种双膦酸酯的配体特性，即与硬金属中心 M2+（M=Ca、UO2）和 M3+（M=La、Ce、Sm、Eu）形成配位聚合物。所有配位聚合物都通过单晶 X 射线衍射、红外光谱和燃烧分析进行了表征。此外，还利用多核核磁共振光谱对配体进行了表征。
Coordination Polymers based on the Neutral Ditopic Ligand (C6H4PO(OCH3)2)2 Involving some f-Block Elements.
An improved synthesis using microwave heating affords (C6H4PO(OCH3)2)2 in excellent isolated yield (95 %). The ligand properties of this bisphosphonateester were explored towards hard metal centers M2+ (M = Ca, UO2) and M3+ (M = 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.
期刊介绍：
ZAAC is an international scientific journal which publishes original papers on new relevant research results from all areas of inorganic chemistry, solid state chemistry, and co-ordination chemistry.
The contributions reflect the latest findings in these research areas and serve the development of new materials, such as super-hard materials, electrical superconductors, or intermetallic compounds. Up-to-date physical methods for the characterization of new chemical compounds and materials are also described.
