摘要	Lanthanide 2,3-pyrazinedicarboxylate complexes with three-dimensional frameworks, [Ln(2)(pzdc)(3)(H2O)]x.2xH(2)O [Ln = Pr (2), Nd (3), and Eu (4)], were obtained by hydrothermal reactions of 2,3-pyrazinedicarboxylic acid (H(2)pzdc) and the lanthanide(III) chlorides, while [La-2(pzdc)(3)(H2O)](x).2xH(2)O (1) was obtained by hydro(solvo)thermal reaction of LaCl3.7H(2)O and 2,3-pyrazinedicarboxylic acid. They are isomorphous and exhibit complicated 3-D structures based on [Ln(2)(pzdc)(3)(H2O)] building blocks. In the asymmetric unit, the two Ln(3+) ions are both nine-coordinate, but with different coordination environments. The ligand pzdc coordinates to the central Ln(3+) ions in a tetradentate, hexadentate, or heptadentate manner. Utilizing the characteristic of Eu3+ ion to act as a conformational probe, we determined the high-resolution spectra of 4, which show that there are two Eu3+ ion sites in the coordination polymer. This is also in agreement with the results of the X-ray single-crystal diffraction study. It was concluded that there are two La3+, two Pr3+ and two Nd3+ ion sites in polymers 1, 2, and 3, respectively. The thermogravimetric analyses of these complexes show that all coordinated and uncoordinated water molecules were lost at the first weight loss above 240 C. (C) Wiley-VCH Verlag GmbH & Co.
