摘要：

Coordination polymers, [Sm-2(Pzdc)(3)(H2O)] (x) center dot 2xH(2)O (I) and [Nd-2(Pzdc)(3)(H2O)] (x) center dot 2xH(2)O (II), were obtained by hydrothermal reactions with 2,3-pyrazinedicarboxylic acid (H(2)Pzdc) and the salts nitrates, and characterized by single crystal X-ray structure, thermogravimetric analysis, element analysis and infrared spectroscopy. The X-ray crystal diffraction data indicates that two complexes crystal in a monoclinic system with the space group P2(1)/c, of the three dimensional framework. The Pzdc ligand in the complexes I and II adopts tetradentate, hexadentate, and heptadentate bridging modes. The influences of coordination modes of the Pzdc ligand on the superstructural diversity is discussed. The photoluminescent data suggest that the ligands act as efficient "antennas" sensitizing the luminescence of the Sm3+ ion. Complex I exhibits strong fluorescent emission bands in the solid state at room temperature.
