摘要：

Six rare-earth (RE) metal constructed 3D metalorganic frameworks, [RE(pydc)(H2O)n]4[SiW12O40]center dot 4H2O [RE = TmIII (1), YIII (2), PrIII (3), LaIII (4), SmIII (5), EuIII (6); n = 3 (1, 2), 4 (36); H2pydc = pyridine-2,6-dicarboxylic acid], have been synthesized and characterized by elemental analyses, inductively coupled plasma techniques, IR and UV spectroscopy, thermogravimetric analyses (for 1 and 3), X-ray powder diffraction, and single-crystal X-ray diffraction. The structural analyses indicate that 16 are basically isostructural and show a rare host 3D framework that contains [SiW12O40]4 Keggin polyoxoanions as templates. Photoluminescence measurements reveal that 15 show the luminescence of pydc ligands, whereas 6 displays a unique red luminescence.
