Abstract: The synthesis, structure, and gas adsorption properties of three new metal-organic frameworks (MOFs) designed from isonicotinic acid (INA) and its fluorinated analogue 3-fluoroisonicotinic acid (FINA) along with Co II as the metal center have been reported. Co-INA-1 ([Co 3(INA) 4(O)(C 2H 5OH) 3][NO 3]̇C 2H 5OḢ3 H 2O; INA=isonicotinic acid) and Co-INA-2 ([Co(INA) 2]̇DMF) are structural isomers as are Co-FINA-1 ([Co 3(FINA) 4(O)(C 2H 5OH) 2]̇H 2O; FINA=3-fluoroisonicotinic acid) and Co-FINA-2 ([Co(FINA) 2]̇H 2O), but the most important thing to note here is that Co-INA-1 and Co-FINA-1 are isostructural as are Co-INA-2 and Co-FINA-2. The effect of partial introduction of fluorine atoms into the framework on the gas uptake properties of MOFs having similar structures has been analyzed experimentally and computationally in isostructural MOFs.
