Sweet solution : The P 2 1 / n ( Z =64) structure of the commercial sweetener sodium saccharinate, which has an unusually large unit cell of 15.6 nm 3 , is an occupational and displacive modulation of an idealized C 2/ m ( Z =8) structure that results from a structural misfit. This determination (see picture) shows—after more than 150 years of use of the compound as a food additive—that it is better regarded as a 1.875 hydrate than a dihydrate.
