Abstract:

By employing the N'-(2,4-dihydroxybenzylidene)-isonicotinohydrazide ligand to assemble with zinc ions in different solvents, the two metal-organic frameworks(MOFs) 1 and 2 were obtained, namely[(dhbi)2Zn2·8H2O]n(1) was obtained from the ligand assemble with Zn(ClO4)2·6H2O, {[(dhbi)2(H2O)2Zn2]·4DMF]}n(2) was obtained from the ligand assemble with Zn(NO3)2·6H2O using diffusion technology of saturated vapor. Single crystal diffraction was used to characterize their structures. Thermogravimetric analysis(TG-DTA) and powder X-ray diffraction(PXRD) were used to measure their thermal stability and purity. The results of vapor adsorption for MeOH indicate that complex 1 is a kind of satisfactory microporous material, further the complex 1 shows 38.1% void volume, and the complex 2 shows 5.5% void volume according to PLATON calculations.
