Polymorphism in acesulfame sweetener: structure-property and stability relationships of bending and brittle crystals

Chem Commun (Camb). 2010 May 28;46(20):3562-4. doi: 10.1039/c0cc00028k. Epub 2010 Apr 27.

Abstract

Acesulfame is found to exist in two crystalline forms of which Form I (needles) shows bending upon mechanical stress. Crystal structures explain their mechanical response. This is the first case of aliphatic organic compounds featuring a bending phenomenon. Form I is physically more stable than Form II in ambient conditions.
