Abstract

Two new MOFs (metal-organic frameworks), namely (3)(infinity)[Cu-2(H2O)(2)(L)]center dot 3DMF center dot H2O [L = 4-fluoro-biphenyl-3,3 ',5,5 '-tetracarboxylate (4-mF-BPTC4-) and 4,4 '-difluoro-biphenyl-3,3 ',5,5 '-tetracarboxylate (4,4 '-dF-BPTC4-)] termed UoC-1(1F) and UoC-1(2F) (UoC equivalent to University of Cologne), were synthesized by solvothermal reactions in DMF. The crystal structure of UoC-1(1F) was solved and refined from X-ray single crystal data (Imma, Z = 4). The X-ray powder diffraction data of UoC-1(2F) confirmed that both MOFs are isostructural. In their crystal structures each of the four carboxylate groups of the BPTC4- linker is involved in a Cu-2 paddlewheel unit leading to a 3D structure with high porosity, which was confirmed by N-2 gas sorption measurements revealing specific surface areas of S-BET = 1256 m(2)center dot g(-1) [UoC-1(1F)] and 1162 m(2)center dot g(-1) [UoC-1(2F)] after activation at 120 degrees C for 72 h. Higher activation temperatures lead to a decomposition of the framework and significantly decreased specific surface areas.
