Abstract: <span style="mso-bidi-font-size:14.0pt;letter-spacing: -.1pt" lang="EN-GB">A new two-fold interpenetrated 3D bi-pillared framework, {[Zn(1,4-bdc)(azbpy)]∙DMF}<i style="mso-bidi-font-style:normal"><sub>n<b style="mso-bidi-font-weight:normal"> </b></sub></i>(<b style="mso-bidi-font-weight:normal">1</b>), where 1,4-bdc = 1,4-benzene dicarboxylic acid, azbpy = 4,4′- azobipyridine and DMF = N,N-dimethyl formamide, has<span style="mso-bidi-font-size:14.0pt" lang="EN-GB"> been synthesized from a mixed ligand system and characterized by single crystal as well as powder X-ray diffraction and thermogravimetric analysis. The metal center, Zn(II), having a trigonal bi-pyramidal geometry, is connected to the three different 1,4-bdc linkers in the equatorial positions while the axial positions are occupied by the two different 4,4′-azbpy pillars.<span style="mso-bidi-font-size:14.0pt" lang="EN-GB"> The framework contains one-dimensional rectangular shaped channels along the <i style="mso-bidi-font-style:normal">c</i> axis and the channel surfaces are decorated with the nitrogen atoms of –N=N- functional group from azbpy ligand. The desolvated framework has a specific surface area of ~ 40 m<sup>2</sup> g<sup>-1</sup> and shows excellent selective uptake of CO<sub>2</sub> at 195 K among other small gases like Ar, N<sub>2</sub> and H<sub>2</sub>- (<b style="mso-bidi-font-weight:normal">1</b>) also adsorbs acetonitrile and benzene solvent vapors at 298 K. </span></span></span>
