STOE USER TALK: STRUCTURE DETERMINATION OF [NH4][SeCN] AND ITS REACTIVITY TOWARDS Ag[SeCN]

About 200 years ago, ammonium cyanate, [NH4][OCN], was obtained by Liebig and Wöhler as a fluffy, white powder from the reaction of dry ammonia with cyanic acid. They also noticed its rearrangement at room temperature into urea, [NH2]2CO, a compound which has the same sum formula as ammonium cyanate.[1,2] From this the concept of isomerism was deduced and remains unchanged until today […]
