Table . Results of the linear regression of the bdc calibration curve presented in Figure . The qNMR integration for the MOF-5 sample yields a bdc/MA ratio of 2.165440. After correction we calculated the amount of moles, the number of moles per mass and finally, with input from TGA we obtain a stoichiometric ratio of 1:0.73 Zn:bdc, which is close to the theoretical ratio of 3:4.
