Abstract

A new 3D inorganic-organic hybrid framework microporous material Na 2Co(1,4-napdc)2(DMF)2(1,4-napdc = napthalene-1,4-dicarboxylate), which is constructed by coordination of cobalt ion and sodium ions with napthalene-1,4-dicarboxylate and DMF, is synthesized under solvothermal conditions. Two bidentate-bridging and two chelate-bridged carboxylate link a cobalt (II) and two sodiums (I) to the dimer structure. The square grids constructed with the caged-laddered-shaped secondary building units (SBUs) built by Co-O-Na-O and Co-O-C-O bond and 1,4-napdc links stack over each other to generate infinite 3D networks, which have a microporous channel (11.05 × 11.05 Å2) along the crystallographic c-axis. The thermal stability of the compound was investigated by differential scanning calorimetric and thermogravimetric analysis. The complexes could be anticipated as potential heat-resistant energetic material.
