77_10/2012Cover Picture: The Reactivity of 5-Cyanotetrazole towards Water and Hydroxylamine (ChemPlusChem 10/2012)

The cover picture outlines the formation of 5-cyanotetrazole from sodium azide and sodium cyanide, which can be further converted into its hydrolysis products tetrazole-5-carboxamide and tetrazole-5-carboxamide oxime. Both products were deprotonated to form the respective hydroxylammonium salts. Among other nitrogen-rich salts of tetrazole-5-carboxamide oxime, they were structurally characterized. The silver salt of 5-cyanoetetrazole is an example of rarely described crystal structures of silver tetrazolate salts. A full account can be found in the Full Paper by T. Klapötke and co-workers on page 877 ff.
