Figure 6
(a) Superposition of the structures (piracetam polymorphs and hydrates) and (b) superposition of all the structures (polymorphs, hydrates, metallic coordination complexes and cocrystals and the structure of this work). Performed by superimposing the five-piece ring of the piracetam molecule.
