Nifedipine (NIF) molecules (L-type calcium channel antagonists) pack in solvated structures showing strikingly similar patterns, see Jones et al. [Acta Cryst. (2023), B79, 164-175]. How much do molecular shapes, such as the NIF molecule which resembles the letter T, matter in their associations in crystals?
Keywords: nifedipine; pharmaceutical; polymorphism; solvate.
