摘要：
Two new europium (III) coordination polymers formulated as Eu-2(H2O)(2)(ox)(4)]center dot(C5H6N)(2)center dot 2H(2)O (1) and Eu-2(ad)(3)(H2O)(4)]center dot 0.25H(2)O (2) (H(2)ox = oxalic acid, H(2)ad = adipic acid) have been synthesized from the self-assembly of lanthanide ions Eu3+ with flexible oxalic and adipic acid ligands, respectively. Structural analyses revealed that complex 1 exhibits three-dimensional metal-organic 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 D-5(0) -> F-7(2) transition of Eu3+ ions.
