Solid-state structure and temperature/evacuation-induced dehydration of sodium saccharinate 1.875 hydrate

Abstract

Sweet solution: The P21/n (Z=64) structure of the commercial sweetener sodium saccharinate, which has an unusually large unit cell of 15.6 nm3, is an occupational and displacive modulation of an idealized C2/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. Show more
