Dear friend Sheetal Tresa Fernandes
According to a post on **ResearchGate**, the best method to grow crystals for organic heterocyclic compounds is to first dissolve the compound in either ethyl acetate or acetonitrile or DMF by warming, allow it to cool in the freezer for 24 hours or more time. You will get the crystals (https://www.researchgate.net/post/Can_anyone_please_suggest_the_best_method_to_grow_the_crystals_for_organic_compounds).
Another method that works well is to dissolve 50-100 mg of each compound in small (5 mL) vials in the minimum amount of organic polar solvent (https://www.researchgate.net/post/Can_anyone_please_suggest_the_best_method_to_grow_the_crystals_for_organic_compounds).
The **Center for Xray Crystallography** suggests that evaporation is the most common methodology for crystal growth. This involves simply evaporating solvent from the solution of the compound until saturation is reached and crystals form. However, this method is not the best and often leads to ugly crystals since the crystals tend to grow on the surface of the vessel (https://xray.chem.ufl.edu/helpful-information/crystal-growing-tips/).
I hope this information helps you. Let me know if you have any other questions.
