There are several ways to synthesize MOF-5.

(i) Room temperature synthesis (Mild route): Zn(NO3)2.6H2O and H2BDC was taken in 1:1 ratio in DMF under constant stirring for ~15 minutes followed by sonication for next 15 minutes for complete dissolution of the starting precursors. Now TEA (tetraethyl amine) was added under agitation and stirring was continued for next 3 hrs in a sealed capped vessel. The white product was collected by centrifugation, washed with DMF and dried under vacuum.

(ii) Solvothermal route: Here Zn(NO3)2.6H2O and H2BDC was taken in 1:1 ratio in DMF and sonication was done for ~15 minutes. Now the clear solution mixture was taken into a teflon lined autoclave, which was then heated under 100 deg C for 24 hrs. Finally it was cooled to room temperature. Solids were collected by centrifugation, washed with DMF and vacuum dried. Good quality single crystals were produced by this way.

TEA is triethyl amine. Not tetra ethyl amine.
