A new three-dimensional porous framework [Co-2(bpdc)2(H(2)bpz)center dot 2(DMF)center dot 5(H2O) (1) (H2bpdc=4,4'-biphenyldicarboxylic acid, H(2)bpz=3,3',5,5'-tetramethyl-4,4'-bipyrazole) has been solvothermally synthesized by employing mixed H(2)bpdc and H2bpz ligands. 1 is a pillared-layer framework based on a binuclear paddlewheel Co2(Co2(O2C-R-4)4 cluster, and exhibits a 2-fold interpenetrated 6-connected pcu topology. H2bpz bridges Co-2(O2C-R)(4)clusters with an angular coordination configuration to form interesting left- and right-handed helical chains. 1 possesses a two-dimensional porous system decorated by uncoordinated pyrazole -NH groups of H2bpz, leading to high adsorption selectivities for CO2 over N-2 and H-2. In addition, the strong antiferromagnetic interactions between the Co2+ ions in cluster were observed.
