| 摘要: 合成并表征了3个同构的稀土二膦酸化合物Ln(hpyedpH2)(hpyedpH3)·2H2O [Ln=Gd (1)，Eu (2)，Tb (3)；hpyedpH4=1-hydroxy -2-(3-pyridyl)ethylidene-1，1-diphosphonic acid，C7H11NO7P2]，测定了化合物1的单晶结构。发现它们具有链状结构，其中Ln通过3个或4个O-P-O基团交替连接，链与链之间存在氢键和π-π堆积作用。探讨了化合物2和3的荧光性质。 |

| Abstract: Three isomorphous complexes Ln(hpyedpH2)(hpyedpH3)·2H2O [Ln=Gd (1), Eu (2), Tb (3)], where hpyedpH4 is 1-hydroxy-2-(3-pyridyl)ethylidene-1,1-diphosphonic acid (C7H11NO7P2), have been prepared under hydrothermal conditions. All show a one-dimensional linear chain structure in which the Ln atoms are alternatively bridged by four and three O-P-O units. The chains are held together through extensive hydrogen bond interactions and π-π contacts between the pyridyl groups, hence generating a three-dimensional network. The luminescent properties of complexes 2 and 3 are investigated. CCDC: 642506. |
