Two structurally different praseodymium-organic frameworks with permanent porosity

• Two lanthanide-organic frameworks based on 2,6-naphthalenedicarboxylic acid
• 2D sheet and 3D rod-packing of microporous lanthanide-organic frameworks
• Permanent porosities of lanthanide-organic frameworks

Two Praseodymium-organic frameworks, [Pr2(NDC)2(NO3)2(DMA)4] (1) and [Pr3(NDC)4.5(DMF)3(H2O)] (2) (H2NDC = 2,6-naphthalenedicarboxylic acid; DMA = N,N-dimethylacetamide; DMF = N,N-dimethylformamide) have been synthesized and structurally characterized. The discrete Pr2(COO)4 cluster and 1D [Pr(COO)3]n rod act as the secondary building units in MOF 1 and MOF 2, respectively, leading to their different structures of 2D sheet and 3D rod-packing. Their permanent porosities have been also established.

Two new microporous lanthanide-organic frameworks based on 2,6-naphthalenedicarboxylic acid have been synthesized and structurally characterized exhibiting permanent porosities.Figure optionsDownload as PowerPoint slide
