摘要

Two new europium （Ⅲ） coordination polymers formulated as Eu2（H2O）2（ox）4 ]· （C5H6N）2 ·2H 2 O（1） and Eu 2（ad）3（H2O）4 ]·0.25H2O （2） （H2ox = 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 5 D0 → 7 F 2 transition of Eu3＋ ions.
