Resolving a Nearly Two-Centuries-Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide. [PDF]
ChemistryThe crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.
