【摘要】 通过(R)/(S)-1-(苯乙基-氨基)甲基膦酸与金属离子的水热反应,我们合成了两个新颖的管状金属膦酸化合物(R)-[Mg(pemp)(H2O)2](1)和(S)-[Mg(pemp)(H2O)2](2)。配体pemp2-的每一个{CPO3}四面体单元通过三个膦酸O原子,与三个{MgO5N}八面体单元共顶点,从而组成了一条无机纳米管。在管内部是亲水的,存在较强的氢键,管外部则是疏水的。在三维空间内,晶体主要通过范德华力作用堆积而成。更多还原

【Abstract】 In this paper,two novel tubular metal phosphonate compounds named(R)-[Mg(pemp)(H2O)2](1)and(S)-[Mg(pemp)(H2O)2](2)based on(R)/(S)-(1-phenylethyl-amino)methylphosphonic acid(pempH2) have been obtained by hydrothermal reactions.Each {CPO3} tetrahedral units on the ligand pemp2-and three {MgO5N} octahedral unit of vertices are corner-shared with through phosphonate O atom to constitute an inorganic nanotube.The interior of the tube is hydrophilic,which has a strong hydrogen bond,and the external of the tube is hydrophobic.The crystal piled up mainly through van der Waals force in three-dimensional space.更多还原
