We achieved a dense I1O3 hybrid superhydrophobic porous coordination polymer (PCP), [Pb­(H-BTMB)­(DMF)] (1), by solvothermal methods. The single-crystal XRD structure of 1 indicated that it has a three-dimensional M–L–M framework with one-dimensional M–O–M connectivity leading to an I1O3 network. The new PCP obtained exhibited open metal sites (OMSs) by losing a coordinated DMF molecule. The degassed phase displayed selective adsorption of CO2 gas over N2, C2H6, and C2H4 gases. Additionally, it has a superhydrophobic surface with a contact angle of 156.4° at room temperature and it is stable even at 90 °C, displaying a contact angle of 135.3°.
