A new three-dimensional porous framework [Co{sub 2}(bpdc){sub 2}(H{sub 2}bpz)]∙2(DMF)·5(H{sub 2}O) (1) (H{sub 2}bpdc=4,4′-biphenyldicarboxylic acid, H{sub 2}bpz=3,3′,5,5′-tetramethyl-4,4′-bipyrazole) has been solvothermally synthesized by employing mixed H{sub 2}bpdc and H{sub 2}bpz ligands. 1 is a pillared-layer framework based on a binuclear paddle-wheel Co{sub 2}(O{sub 2}C-R){sub 4} cluster, and exhibits a 2-fold interpenetrated 6-connected pcu topology. H{sub 2}bpz bridges Co{sub 2}(O{sub 2}C-R){sub 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 H{sub 2}bpz, leading to high adsorption selectivities for CO{sub 2} over N{sub 2} and H{sub 2}. In addition, the strong antiferromagnetic interactions between the Co{sup 2+} ions in cluster were observed. - Graphical abstract: A new pillared-layer porous framework has been constructed by paddle-wheel Co{sub 2}(O{sub 2}C-R){sub 4} cluster and H{sub 2}bpdc–H{sub 2}bpz mixed ligands, displaying adsorption selectivity and antiferromagnetic properties. Display Omitted - Highlights: • We present a new pillared-layer framework based on paddle-wheel Co{sub 2}(O{sub 2}C-R){sub 4} cluster. • The framework possesses a 2-fold interpenetrated pcu topology. • The framework displays adsorption selectivity and antiferromagnetic properties.
