A metal-organic framework, Zn3(OH)( BDC-2,5-Cl2)2.5(DMF)3(H2O) 1 (BDC-2,5-Cl2 = 1,4-benzenedicarboxylate-2,5-dichloro and DMF = N,N -dimethylformamide) of rare five-connected (44)(66) topology was synthesized and structurally characterized. The framework is thermally stable up to 350 C, thus activation of this new MOF material at different temperature of 150 and 300 C under high vacuum formed two microporous materials 1a and 1b, respectively, exhibiting selective gas adsorption behavior with respect to H2/N2 and O2/N2, and CO2/CH4 and CO2/N2.
