摘要：

Two new three-dimensional lanthanide coordination complexes, [Ln(2)(IDC)(2)(H2O)(3)] center dot 1.5H(2)O (Ln = Sm (1), Eu (2), IDC = 4,5-imidazoledicarboxylate), have been prepared by hydrothermal reaction of Ln(2)O(3), H3IDC at 140 degrees C and characterized by single-crystal X-ray diffraction analysis. To our knowledge, they represent the first examples of having intertwined lanthanide double and triple helical motifs and nanosized tubular channels. In addition, compound 2 exhibit red photoluminescence at room temperature. (C) 2005 Elsevier B.V. All rights reserved.
