Figure 9
The molecular dimers corresponding to the strongest intermolecular interactions in the polymorphs of p- and m-nitrophenol. (a) Two hydrogen-bonded molecules in the stable polymorphs of m-nitrophenol (orthorhombic form) and p-nitrophenol (β form); (b) two hydrogen-bonded molecules in the metastable polymorphs of m-nitrophenol (monoclinic form) and p-nitrophenol (α form); (c) two overlapped molecules in the stable polymorphs of m-nitrophenol (orthorhombic form) and p-nitrophenol (β form); (d) two overlapped molecules in the metastable polymorphs of m-nitrophenol (monoclinic form) and p-nitrophenol (α form).
