Two unprecedented porous anionic frameworks: organoammonium templating effects and structural diversification.
Two unprecedented 3D porous anionic metal-organic frameworks, [Me2NH2]2[Cd2(bpdc)3].4dma 1 and [Me2NH2]2[Cd2(NH2bdc)3].4dma 2 (dma = N,N'-dimethylacetamide, bpdc = 4,4'-biphenyldicarboxylate, NH(2)bdc = 2-amino-1,4-benzenedicarboxylate) have been solvothermally synthesized with a dimethylammonium cations template. Both 1 and 2 are constructed from low-symmetry SBUs. 1 has a chiral framework with helical nanotube-like channels, and 2 has a MOF-5-like motif. The fluorescence, N2 adsorption and ion-exchange properties for 1 have been examined.
