| Abstract: | 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 Å3). 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. |
