| 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.
