Polymorphs often have different values of Z ′, the number of independent molecules in the asymmetric unit of the crystal structure. Structures with Z ′ > 1 are a small minority, particularly so for Z ′ > 2, and many are associated with packing problems, disorder and weak intermolecular interactions. These phenomena are fascinating and have important practical implications.
