摘要：

The slow diffusion through gel in a U-tube of trivalent lanthanide ions with TMA(3-), where TMA(3-) stands for [C6H3(COO)(3)](3-) afforded single crystals suitable for crystalline resolution. The crystal structure has been solved for the Ce(III) compound and is reported here. The chemical formula is Ce-2(CO3)(3).8 H2O and the space group of the crystalline structure is Pccn with: a=8.9321(7) Angstrom, b=9.5292(9) Angstrom, c=16.971(2) Angstrom and Z=4. The structure consists in planes in which the lanthanides ions are connected via bidendate carboxylato groups or mu (2)-oxo bridges. The isostructurality of the other compounds has been assumed on the basis of X-ray powder diagram and elementary cell determination. (C) 2001 Elsevier Science B.V. All rights reserved.
