摘要：

Pyridine-2,6-dicarboxylic acid (H(2)PDA) reacted with DY2O3 under hydrothermal conditions to form a novel lanthanide-organic framework [Dy-2(PDA)(3)(H2O)(4)](n) center dot 6nH(2)O (1)- Compounds I crystallizes in monoclinic system, space group P21/c. In 1, a square motif as a building block constructed by four Dy3+ ions was further assembled into a highly ordered 2D (4,4) grid. While the self-assembly of H(2)PDA and SM2O3 under hydrothermal conditions produced [Sm-2(PDA)(3)(H2O)(6)](n) center dot 2nH(2)O (2). Compound 2 crystallizes in triclinic system, space group P-1, and shows a 1D coordination polymeric chain built from dimeric units of Sm3+ ions. Furthermore, the luminescent properties of both I and 2 were studied. (c) 2008 Published by Elsevier B.V.
