摘要

Two new europium （Ⅲ） coordination polymers formulated as Eu2（H20）a（ox）4]· （CsH6N）2-2H20 （1） and Eu2（ad）3（H20）4]＇0.25H20 （2） （H20x = oxalic acid, H2ad = adipic acid） have been synthesized from the self-assembly of lanthanide ions Eu^3＋ with flexible oxalic and adipic acid ligands, respectively. Structural analyses revealed that complex 1 exhibits three-dimensional metalorganic frameworks, and 2 has intricate two-dimensional interpenetrated metal-organic networks. In addition, the photoluminescent properties of complexes 1 and 2 were discussed in detail, which shows strong red emission, corresponding to ^5Do →^7F？ transition of Eu^3＋ ions.
