A three-dimensional (3D) porous metal organic framework namely, {[Cu-3(N-3)(2)(4-ptz)(4)(DMF)(2)]center dot 2DMF}(n), has been synthesized using Cu(CH3COO)(2)center dot H2O and ligand 4-ptz [5-(4-pyridyl)-tetrazolate] which was formed in situ from 4-cyanopyridine and sodium azide in presence of water and Cu-parallel to ions. Crystal structure analysis showed that the complex crystallizes in the monoclinic space group P2(1)/c and has a decorated body centred cubic (bcu) topological net with 8-connected Cu3 cluster as node. Magnetic studies exhibit prominent antiferromagnetic interactions influenced by EO (end on) azide and mu(2),eta(2)-tetrazolato bridge among the metal centres. Gas adsorption studies reveal moderate carbon dioxide uptake, which is also reflected in the isosteric heat of adsorption (Q(st)) value of -28 kJ mol(-1)
