Abstract

The reaction of Cd(NO₃)₂·4H₂O and Zn(NO₃)₂·6H₂O with the bipyridyl dicarboxylate ligand H₂bpydc (2,2′-bipyridine-4,4′-dicarboxylic acid) afforded two porous metal organic frameworks [Cd(bpydc)₂(DMF)₂·2DMF]_n (JMS-3) and [Zn(bpydc)(DMF)·DMF]_n (JMS-4). X-ray diffraction studies revealed that both JMS-3 and JMS-4 crystallize in the monoclinic crystal. The MOFs possess 2D interdigited networks with (sql) topology. Sorption studies showed that the activated phase of JMS-3 had CO₂ volumetric uptakes of 26.50 and 30.89 cm³ (STP) g⁻¹ (1.18 and 1.39 mmol g⁻¹) whist JMS-4 gave 10.96 and 16.08 cm³ (STP) g⁻¹ (0.49 and 0.71 mmol g⁻¹) at 298 and 273 K respectively.
