Synthesis, characterization and catalytic studies od a new two-dimensiional metal-organic framework based on Co-carboxylate secondary building units

A metal-organic framework [Co3(BDC)3(DMF)2(H2O)2] was synthesised and structarally characterized. Y-ray single crystal analysis revealed that the framework contains a 2D polymeric chain through coordination of 1, 4-benzenedicarboxylic acid linker ligand to cobalt center. The polymer crystallize in monoclinic P21/c space group with a=13.989(3)A, b=9.6728(17)A, c=16.707(3)A, Z=2. The polymer features a framework based on the perfect octahedral Co-O6 secondary building units. The catalytical acivities of [Co3(BDC)3(DMF)2(H2O)2]n for olefines oxidation was conducted. The heterogeneous catalyst could be facilely separated from the reaction mixture, and reused three times without significant degradation in catalytic activity. Furthermore, no contribution from homogeneous catalysis of active species leaching into reaction solution was detected.
