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.

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.
