A quarter of the unit cell volume of [{Ni(4,4′‐dipy)(3‐nitrobenzoate) 2 (MeOH) 2 } n ], which crystallizes in the form of helices, is occupied by large chiral cavities (400–500 Å 3 ). The cavities are capable of encapsulating not only single molecules, but also face‐to‐face dimers of nitrobenzene (see stick model). 4,4′‐dipy=4,4′‐bipyridine.
