Crystal polymorphism, which embodies the ability of molecules to form diverse packing arrangements displaying different physical and chemical characteristics, is of paramount importance in fields such as pharmacology, solid-state chemistry, and material science. However, the conditions to induce the precipitation of various (metastable) polymorphs is invariably achieved by “mix and try” methods, which are kinetically driven. Various factors should be considered in trying to understand these… CONTINUE READING
